Knit is a stablecoin payments infrastructure company built for businesses that need to send, receive, and manage digital assets across borders without the complexity of maintaining in-house blockchain engineering. Operated by Knit Business Financial Services Ltd. and headquartered in Toronto, Canada, the company launched in April 2024 and positions itself at the intersection of regulated finance and programmable money.

What Knit Does

At its core, Knit provides a unified JSON API that abstracts on-chain payment flows into familiar business primitives: collect, hold, and disburse. Instead of requiring finance teams or developers to reason about gas fees, wallet key management, or chain-specific quirks, Knit exposes a single interface that handles the underlying complexity.

The architecture follows a clear three-step flow. Incoming funds arrive at single-use deposit addresses or long-lived reusable wallets. Confirmed deposits credit a central API account — an aggregated balance that functions like a programmatic treasury. From there, businesses trigger on-chain payouts to any external address, with webhook callbacks reporting final settlement state. Every event can be verified via webhook signatures, and address-watching notifications alert operators to incoming or outgoing activity in real time.

Wallet Types and Treasury Tools

Knit offers three distinct wallet configurations suited to different operational models.

The Business Wallet provides managed services for companies integrating Knit into existing payment flows — suitable for businesses that want infrastructure without direct custody responsibility. The Trust Wallet handles managed cryptocurrency payment processing, where Knit takes on the operational layer. The Vault Wallet is an independent, trustless option for businesses that want to retain direct control over their assets without relying on a managed signing policy.

Treasury management sits across all three: API accounts aggregate incoming collections and fund outbound payouts, giving operators a centralised on-chain balance that can be queried and moved programmatically.

Supported Chains and Assets

Knit currently supports six blockchain networks: Ethereum, Tron, Polygon, Base, and BNB Smart Chain (BSC), with a sixth network available via its supported-networks API endpoint. The primary settlement assets are USDT and USDC — the two dominant dollar-pegged stablecoins — which keeps currency risk out of the picture for businesses operating in fiat-equivalent terms.

Solana is not currently supported. For teams specifically seeking stablecoin payment rails on Solana — where native USDC through Circle's infrastructure, SPL token transfers, and sub-second finality are available — Knit does not yet offer a path. This is a meaningful gap given Solana's growing traction for high-throughput payment applications, and it is worth tracking whether the platform expands its chain coverage.

Compliance and Licensing

Knit is registered with Canada's Financial Transactions and Reports Analysis Centre (FINTRAC) as a Money Service Business under registration number C100000256. This is a legally mandated registration for entities in Canada that deal in virtual currencies, and it requires adherence to anti-money laundering and counter-terrorist financing obligations.

The compliance infrastructure extends into the product itself. Knit automates KYC checks for onboarding businesses and their Ultimate Beneficial Owners, and AML guidelines are embedded into the account approval process. For finance teams that need to demonstrate regulatory compliance to auditors or banking partners, the FINTRAC registration provides a meaningful anchor.

Developer Experience and Integration

The API uses OAuth 2.0 client credentials for authentication, with scoped access tokens and a unified JSON envelope across all endpoints. Camelcase field naming and consistent response shapes (statusCode, message, data, success) make the integration surface predictable. Knit provides a pre-production environment at api-dev.useknit.io alongside the production base URL, allowing teams to test payment flows before going live.

Beyond raw API access, Knit supports payment link generation — shareable links that merchants can distribute for invoices or checkout flows — and multi-signature wallet controls with policy-governed transaction signing. For teams building on top of the platform, managed signing means transaction approval policies can be enforced programmatically rather than relying on individual key holders.

Metrics and Market Context

Knit reports $100 million in transactions processed and $8 million in assets under custody since launching in April 2024. Both figures are self-reported on the company's marketing site without third-party verification, but the scale suggests meaningful early adoption for a platform less than two years old.

The company operates in a market that has seen significant institutional interest. Stablecoin payment volumes have grown sharply as businesses seek to reduce correspondent banking costs and settlement latency for cross-border payments. Knit's positioning — regulated, API-first, stablecoin-native — mirrors approaches taken by players like Bridge (acquired by Stripe in late 2024) and BVNK, but with a focus on the Canadian regulatory context and a broader emerging-market remittance use case.

The platform's multi-chain approach reflects the fragmented nature of stablecoin liquidity today: USDT dominates on Tron for many remittance corridors, while USDC and Ethereum-based stablecoins are preferred in institutional and DeFi-adjacent contexts. By supporting both assets across multiple networks, Knit avoids locking business customers into a single liquidity pool.

Whether Knit eventually adds Solana support will matter for its long-term positioning — Solana's USDC volume and payment developer ecosystem have expanded considerably, and any infrastructure provider that wants full market coverage will need to engage with it.
