Blockroll

Blockroll is a consumer fintech application designed to solve a concrete pain point: African freelancers and remote workers routinely absorb fees of six to nine percent per transaction when receiving international payments, and settlements can take days. Blockroll positions itself as a global account that collapses those costs to near-zero and reduces settlement time to under five minutes by routing stablecoin transfers across Solana and other blockchain networks on the backend.

Problem and Context

Freelancers and independent contractors in sub-Saharan Africa face a structural mismatch between where they earn and where they spend. Payments typically arrive in USD via wire transfer or legacy remittance rails, then convert to local currency at unfavorable rates. Each step in that chain — receipt, conversion, local disbursement — carries a fee. For workers whose income depends entirely on cross-border payments, those cumulative losses are material.

Blockroll's founders experienced this friction directly. CEO and co-founder Sadiq Isiaka encountered persistent payment difficulties while leading a Web3 and NFT education project in 2022. Together with CPO and co-founder Stephen Adeyemo, who has a background building fintech products, he set out to build a single app that would handle the full payment lifecycle: invoice generation, international receipt, stablecoin holding, and local spending — without requiring the user to understand or manage blockchain infrastructure.

How It Works

Blockroll presents as a standard mobile banking app but settles international transfers using USDC stablecoins over Solana, Aptos, Base, and Polygon PoS. The stablecoin layer is powered by Circle's wallet infrastructure and USDC issuance; Blockroll is a Circle Alliance partner. Users never interact directly with a blockchain wallet or private keys. They create an account through the app, receive a Pay Tag (a username-based address), and can immediately accept payments in either Naira or stablecoins.

When a client pays an invoice in USDC, the funds arrive in the user's stablecoin wallet within minutes. The user can hold those funds in USDC or USDT, convert them to Naira at the current market rate, or spend directly using the Limitless Card — a virtual USD Visa card issued through Blockroll.

The April 2025 live demonstration of a Naira-to-USDC-on-Solana-to-Naira round-trip confirmed that Solana is one of the active settlement networks. The multi-chain approach reflects a pragmatic design choice: USDC circulates across multiple networks, and routing over whichever chain is fastest or cheapest at a given moment reduces user-facing friction.

Core Features

Multi-Currency Wallets — A single account holds Nigerian Naira, US Dollars, Euros, USDC, and USDT. Users can switch between currencies and convert at live rates without leaving the app.

Pay Tag — A human-readable identifier (similar to a username) replaces wallet addresses and bank account numbers for peer-to-peer transfers. Transfers between Blockroll users using Pay Tags are instant and described as free.

Smart Invoicing — Users generate professional invoices in multiple currencies directly inside the app. Clients can pay in either Naira or stablecoins. Invoices are customizable and can include project details, due dates, and payment methods.

Limitless Card — A virtual USD Visa card for international online purchases and subscription payments. The card draws from the user's USD or stablecoin balance.

Bills Payment — Integrated payments for Nigerian utility categories: mobile airtime, data bundles, electricity, and cable television. These are paid in Naira from the local wallet balance.

Biohub — A professional profile page that aggregates a user's rate card, portfolio links, social accounts, and payment details in a single shareable link. The feature is designed to reduce the back-and-forth of sharing credentials with prospective clients.

Live Analytics — An in-app dashboard tracking income and spending across currencies over time.

Supported Assets

Blockroll supports NGN (Nigerian Naira), USD, EUR, USDC (on Solana, Aptos, Base, and Polygon PoS), and USDT. Fiat balances are held through partnerships with licensed financial institutions; stablecoin balances use Circle's custodial infrastructure.

Team and History

Blockroll, Inc. was incorporated in Delaware in April 2023. The founding team includes Sadiq Isiaka (CEO, background in product management and UX research), Stephen Adeyemo (CPO, fintech product design), and Emmanuel Nwaka (CMO, three-plus years in Web3 digital marketing).

In October 2023, Blockroll was accepted into the Microsoft for Startups Founders Hub program, gaining access to Azure credits, GitHub Enterprise, mentorship, and Microsoft's investor network. The first version of the app accumulated over 1,000 users before the V2 relaunch. The V2 app launched in June 2025 and is available on iOS and Android.

Coverage in Technext24 in August 2025 described the company's mission as "redefining how African freelancers build and earn." The app is listed in Apple's App Store under the Finance category and on the Circle Alliance partner directory.

Security and Audit Status

Blockroll does not deploy its own smart contracts. Stablecoin custody and on-chain settlement are handled by Circle's wallet infrastructure, which carries Circle's own security posture and compliance framework. Blockroll's marketing copy states that the app uses end-to-end encryption and fraud protection for user data and assets. No independent public audit report specific to Blockroll's infrastructure or application layer has been published as of mid-2026.

Solana Ecosystem Fit

Blockroll does not build on Solana in the developer-tooling or DeFi-protocol sense. Its connection to the ecosystem is through stablecoin payment flows: Solana's speed and low transaction costs make it a practical settlement rail for the sub-five-minute transfer promise. For a product category where the user should never see a blockchain, Solana serves as infrastructure rather than identity.

The broader use case — directing stablecoin payment flows toward under-served markets in sub-Saharan Africa — aligns with the direction Circle and other infrastructure providers have identified for USDC adoption outside of DeFi. Blockroll represents that pattern at the consumer layer: a mobile-first application that uses Solana's throughput to deliver fintech functionality that legacy banking rails in Nigeria cannot match on cost or speed.
