Prove Your Stablecoin Corridors End to End

It is a single, end-to-end cross-border payment designed to be proven in practice: fiat is converted into a stablecoin, compliance checks are completed, the transfer settles on a public blockchain, and the funds are converted back into local currency and paid into a local account. The worked corridor is designed around the United Kingdom to Brazil.

On-Ramp converts fiat into stablecoin. Compliance completes sanctions screening and Travel Rule checks before tokens move. Blockchain settles the transfer on a public network with the token backed 1:1 by its issuer. Off-Ramp converts the stablecoin into local currency. Settlement pays the funds into a local bank or mobile-money account.

Sanctions screening and Travel Rule checks are completed at stage two, before any tokens are moved on-chain. Screening the transfer before settlement means a blocked payment never reaches the blockchain leg.

No. Every provider named on this site is an illustrative example of the type of service used at that stage of the corridor. Naming a provider does not imply a partnership, integration or endorsement.

The proof of concept references public networks including Ethereum, Polygon, Solana and Stellar, with USDC (Circle) and USDT (Tether) as the stablecoins. The worked corridor uses USDC as the transfer token.

The proof of concept covers one corridor, from the United Kingdom to Brazil. Other regions shown on this site are indicative of where a corridor could be extended; each additional corridor needs its own on-ramp, off-ramp and compliance coverage.

The payer funds the transfer in their own currency and a licensed on-ramp or exchange converts that fiat into a stablecoin. Illustrative examples of this type of provider include BVNK and Stripe.

Sanctions screening and Travel Rule checks are completed before any tokens move on-chain, so a blocked transfer never reaches the blockchain leg. Illustrative examples of this type of provider include Notabene and Elliptic.

The stablecoin transfer settles on a public network such as Ethereum, Polygon or Solana, typically in seconds. The token issuer, for example Circle for USDC or Tether for USDT, backs the token 1:1 in reserves.

An off-ramp provider receives the stablecoin and converts it into the recipient's local currency. Yellow Card is an illustrative example of this type of provider.

Settled funds are paid into an ordinary local bank account or a mobile-money account, so the recipient does not need to hold or manage any crypto. A local partner bank, or a route such as MoneyGram via Stellar, are illustrative examples.

A UK marketing agency sends GBP, which is on-ramped into USDC. The transfer settles on a public blockchain, is off-ramped into BRL on arrival, and is paid into the local account of a freelancer in Brazil. That endpoint role is played by a Network Partner in the proof of concept.

A verified Network Partner who will provide the endpoints for the final three stages of the corridor, so the flow is designed to be evidenced end to end with real accounts rather than modelled on paper.

Three: an on-chain wallet that can receive the stablecoin leg (stage 3), an account with an off-ramp provider that converts stablecoin into local currency (stage 4), and a local bank or mobile-money account that receives the settled funds (stage 5).

No. The stablecoin is received and off-ramped as part of the corridor run. The purpose of the wallet is to prove the blockchain leg reaches a real endpoint, not to hold a position.
