New tax boundaries and sandbox tracks from Nigerian regulators anchor today's developments, alongside a sweeping draft payment systems bill out of Kenya. Across the broader continent, we are tracking fresh institutional crypto custody infrastructure in South Africa and new multi-currency commercial card rollouts.
Following up on its reserve custody role for the ZARsc stablecoin we covered yesterday, Absa Corporate and Investment Banking launched its own Absa Digital Asset Custody platform on Tuesday, September 22. Utilizing Ripple's institutional custody technology, the platform operates as a regulated, bank-grade vault providing private-key management, multi-layer approval workflows, and governance controls for institutional client digital asset holdings without offering trading or brokerage services directly.
Why it matters
The entry of a major Tier-1 South African bank into digital asset custody establishes the regulated balance-sheet infrastructure required for institutional stablecoin clearing and on-chain FX settlement. By resolving the custodial risk that previously kept corporate treasuries from holding digital assets, Absa creates a compliant domestic anchor for future ZAR-stablecoin settlement rails. Payment gateways serving multinational merchants in South Africa gain a direct institutional counterparty for securing digital asset reserves.
Highlighting the credential friction that drove this week's rollout of verified agentic token standards by major card schemes, Amazon initiated technical blocks against Meta's personal AI shopping agent, Muse. The retailer prevented the bot from completing purchases on Amazon.com after Meta refused to withdraw it from automated browsing flows, noting that Muse was logging into user accounts and browsing as a human user without self-identifying as an automated agent.
Why it matters
This conflict establishes an explicit boundary for autonomous commerce, proving exactly why the sanctioned Know-Your-Agent (KYA) trust frameworks we've been tracking are necessary. Major retail platforms will aggressively block third-party AI agents that rely on browser emulation and session credential scraping. For ecommerce platforms, controlling the checkout API boundary against unverified user-impersonation scripts is now a critical security requirement.
B2B payment platform Verto partnered with Visa on Monday, September 21, to launch the multi-currency Verto Card, enabling corporate clients to transact across 11 primary currencies with zero FX markups on eligible currencies and acceptance across 150 million global merchants. Linked directly to multi-currency Verto wallets, the corporate card supports USD, EUR, GBP, and JPY payables, with plans to release Google Pay integration and a Cards-as-a-Service API.
Why it matters
African merchants importing inventory routinely suffer from double-conversion markups and single-currency card decline rates when settling international software and supplier invoices. By settling transactions directly out of pre-funded multi-currency wallets, this card eliminates intermediary bank FX spread gouging on cross-border payables. The planned Cards-as-a-Service rollout also allows regional fintechs to embed native multi-currency issuing directly into their merchant dashboards.
The Nigerian Communications Commission's Computer Security Incident Response Team (NCC-CSIRT) published a security advisory on Monday, September 21, warning of rogue cellular base stations and IMSI catcher threats targeting financial services. Cybercriminals are using signal-jamming devices and localized fake towers to intercept SMS traffic, capture two-factor authentication OTPs, and execute smishing attacks against mobile banking users.
Why it matters
IMSI catcher attacks bypass application-level encryption and API security by compromising the underlying cellular signaling path, exposing SMS-based OTP authentication as an obsolete security control for high-value financial transactions. Payment gateways and acquirers relying on SMS OTPs for card 3D-Secure or merchant withdrawal authorization face severe account takeover exposure. Fraud teams must accelerate the migration toward hardware passkeys, push authentication, and app-native biometrics.
Fintech platform Kredete announced on Monday, September 21, that it acquired Gravv, an agentic stablecoin infrastructure provider that has processed over $3 billion in annualized volume across seven banking partners. The deal brings Gravv's multi-currency account routing, automated FX liquidity management, and blockchain settlement capabilities natively into Kredete's stack, establishing an autonomous middleware layer for cross-border treasury and payments.
Why it matters
By bringing agentic stablecoin routing in-house, payment providers can bypass third-party aggregator markups and automate real-time multi-currency rebalancing across volatile African FX corridors. The consolidation reflects an operational pivot toward AI-managed treasury logic that matches pre-funding reserves against instant payout demands without manual intervention. For B2B gateways, embedding native stablecoin middleware reduces settlement latency for diaspora and cross-border commercial flows.
The Central Bank of Kenya and National Treasury published the draft National Payment System Policy and National Payment System Bill 2026 on Monday, September 21, initiating a public consultation to repeal the existing Act (Cap. 491A). The draft overhaul introduces updated statutory mandates covering digital payment licensing, interoperability standards, consumer protection, and supervisory powers over non-bank payment service providers.
Why it matters
The proposed legislation modernises Kenya's digital payments baseline, directly affecting cross-border gateways, mobile money aggregators, and remittance providers operating in the country. Strict statutory mandates for technical interoperability and localized data protection will raise the ongoing compliance overhead for foreign payment processors selling into Kenya. Gateways must track the consultation window to assess upcoming changes to PSP licensing categories and settlement reporting rules.
Stablecoin settlement platform Minisend expanded its Kenyan payout operations on Monday, September 21, announcing its role as official payment partner for the Africa Blockchain Festival 2026 in Nairobi. The company deployed a multi-chain routing layer that ingests dollar stablecoins like USDC and USDT from multi-chain wallets and executes instant, automated conversions into local M-Pesa mobile money balances for merchants and freelancers.
Why it matters
Connecting multi-chain stablecoin liquidity directly into M-Pesa payout APIs solves the last-mile conversion friction that usually prevents local merchants from accepting digital asset settlements. By abstracting away underlying gas tokens and exchange order books, these rails allow cross-border merchants to receive dollar-indexed payments while suppliers receive instant spendable shillings. The setup presents a lean alternative to traditional correspondent wire corridors.
KCB Bank Kenya and Airtel Money Kenya launched a merchant payment interoperability integration on Monday, September 21, allowing Airtel Money users to pay directly into KCB merchant tills via Lipa Na KCB paybills. The integration enables direct wallet-to-till routing without forcing customers to transfer funds to KCB accounts first, reducing transaction charges under Kenya's National Payments Strategy 2022-2025.
Why it matters
Direct interoperability between mobile telco wallets and commercial bank acquirer tills removes payment friction for retail merchants who previously had to maintain multiple merchant till accounts. For payment aggregators in East Africa, open wallet-to-bank till routing lowers drop-off rates at checkout and forces competing telcos to lower proprietary paybill processing fees.
The Nigeria Revenue Service published formal Guidelines on Taxation of Virtual Assets on Monday, September 21, establishing tax collection rules for digital asset platforms and peer-to-peer marketplaces. The framework mandates a 1% withholding tax on taxable crypto disposals, 10% on staking and DeFi yields, and a 1.5% stamp duty on fiat-to-token transfers. Crucially, the guidelines explicitly exempt stablecoin sales from the 1% withholding tax requirement.
Why it matters
Carving out stablecoins from withholding tax burdens acknowledges their operational role as commercial payment rails rather than speculative assets. For acquirers and cross-border gateways processing payments in Nigeria, this tax clarity eliminates a major liability risk when routing B2B transactions through stablecoin settlement layers. However, payment processors must update their checkout integration logic to handle the 1.5% stamp duty on local fiat-to-token conversion steps.
Advancing the regulatory sandbox framework we tracked in August, the Central Bank of Nigeria opened applications for Cohort 2 on Monday, September 21. The new cohort maintains the dedicated VASP Track we previously detailed—covering stablecoin settlement and crypto on/off-ramps under SEC Nigeria oversight—while the Non-VASP Track caters to open banking, payment initiation, and fraud tooling.
Why it matters
Creating a dedicated VASP track inside the central bank sandbox establishes a formal, legal testing ground for unlicensed stablecoin aggregators to interface directly with commercial bank clearing channels. This structural split forces builders to choose early between heavy VASP capital and reporting mandates versus lighter payment initiation licensing. For payment gateways, the sandbox provides a pathway to test hybrid fiat-stablecoin checkout products without risking sudden regulatory enforcement.
The Central Bank of Eswatini fully activated the Eswatini Payment Switch fast payments platform on Monday, September 21, establishing 24/7 real-time domestic clearing between commercial banks and mobile money operators like MTN MoMo. Built on ISO 20022 messaging standards, the infrastructure replaces legacy batch EFT clearing with instant inter-bank and wallet transfers, with upcoming phases targeting QR code standardisation and open banking APIs.
Why it matters
Deploying ISO 20022 native messaging across national switches removes the technical friction and multi-hour settlement delays that fragment bank and mobile wallet liquidity in Southern Africa. Standardising on ISO 20022 prepares smaller SACU markets for seamless, direct API integration into regional cross-border rails like South Africa's PayShap and SADC RTGS. Merchant acquirers operating in the region gain standardized endpoints for unified cash collections.
Mauritius Commercial Bank, Export Trading Group, Enigio, and Digital Trade Works executed Africa's first electronic bill of exchange transaction under Mauritian law on Monday, September 21. Utilizing Enigio's trace:original cryptographic technology and Mauritius' Model Law on Electronic Transferable Records (MLETR) legislation, ETG generated five digital negotiable instruments in under 30 minutes and transferred ownership to MCB in under one hour.
Why it matters
Paper-based courier transmission of trade bills historically adds days to cross-border trade settlement and locks up working capital for African trade finance. Demonstrating legally binding, sub-hour electronic bill transfers under MLETR establishes a commercial benchmark for digitising cross-border B2B receivables and trade paper across African trade corridors. B2B payment platforms can leverage this legal precedent to build digital trade invoice discounting modules.
Tax and Sandbox Frameworks Establish Formal Dual-Track Compliance for Digital Assets Regulatory bodies in West Africa are separating digital asset channels into distinct compliance tracks rather than imposing blanket bans. The Nigeria Revenue Service's explicit exemption of stablecoin transactions from 1% withholding tax, combined with the Central Bank of Nigeria's creation of separate VASP and Non-VASP sandbox cohorts, provides clear legal parameters for fintechs operating stablecoin rails alongside conventional payment stacks.
Commercial Banks Institutionalise On-Chain Custody and Direct Multi-Currency Rails Tier-one banking institutions are moving directly into infrastructure layers previously occupied by fintech aggregators. Absa CIB's launch of bank-grade crypto custody using Ripple technology in South Africa, alongside Verto and Visa's launch of multi-currency corporate cards, demonstrates that institutional balance sheets are directly underwriting digital asset storage and multi-currency liquidity for merchants.
ISO 20022 Fast Payment Switches Eliminate Domestic Bank-Mobile Money Silos National monetary authorities in smaller African markets are deploying 24/7 instant payment switches to unify bank accounts and mobile wallets under single interoperable networks. Eswatini's activation of its ISO 20022 fast payments switch and Kenya's KCB-Airtel till integration show that regulatory mandates and technical standardization are systematically dismantling proprietary wallet walled gardens.
Agentic Commerce Enforces Hard API Boundaries at Checkout Retail and payment platforms are taking aggressive technical measures to block third-party AI agents that execute checkout flows via credential scraping or browser emulation. Amazon's decision to block Meta's Muse agent illustrates that checkout infrastructure providers will demand formal, authenticated API protocols like KYA and AgentSafePay rather than unmonitored automated web sessions.
Telecommunications Signal Hijacking Threatens Legacy SMS OTP Security Fraud vectors in regional digital banking are shifting from application-layer credential abuse toward physical telecom signal interception. Advisories from regulatory CSIRTs regarding rogue cellular base stations and IMSI catchers highlight that payment acquirers and issuers relying on SMS for one-time passwords face direct infrastructure compromise, driving the urgency for app-native tokenisation and biometrics.
