Stablecoin payments, built for compliance.
Stablecoin payment rails, checkout, payouts, treasury and compliance tooling, for businesses moving money across borders or to machines.
[ 01 ]The short answer
What is Stablecoin and Crypto Payments?
Stablecoin payment development builds the systems that let a business accept, hold and send dollar-backed tokens such as USDC and USDT: checkout, payouts, treasury, on and off ramps, and the reconciliation and compliance around them. Stablecoins settle in seconds, around the clock and across borders at low cost. With the GENIUS Act's rules arriving, we design sanctions screening, travel-rule data, freeze handling and audit trails into the architecture rather than bolting them on.

[ 04 ]How we deliver
Four steps, one team, start to finish.
The same people scope it, build it and stay after launch. Timings are typical for a first release; we agree yours after the deep dive.
- 01Week 1
Threat model and spec
Who can move money, under what conditions, and what happens when a key, an oracle or a bridge fails. Written down before code.
- 02Weeks 2 to 8
Build with invariants
Contracts or programs with unit, fuzz and invariant tests, least-privilege roles, timelocks and rate limits from the first commit.
- 03Weeks 6 to 10
Review and testnet
Internal review, an independent audit where value is at stake, and a public testnet with monitoring wired in.
- 04Ongoing
Mainnet and watch
A staged launch with caps, live alerting on admin actions and outflows, and a rehearsed incident plan.

The GENIUS Act turns stablecoin compliance into an engineering problem
ProblemStablecoin issuers and payment platforms face new reserve, disclosure, AML, sanctions and freeze obligations, while most stablecoin stacks were built for speed with compliance added by hand.ProposalCompliance by architecture: role-separated freeze and burn powers with audit trails, screening at every edge, travel-rule data in the payment flow, reserve data published on a schedule, and reconciliation that closes daily.Read the proposal - Agent payments4 min read
Agent payments settle on promises. They should settle on proof
Problemx402 and payment channels let agents pay for APIs and compute, but settlement is blind to whether the inference ran, on which model, or how many tokens it really used.ProposalSettle only against two signatures: the agent's spending voucher and a usage receipt signed inside the provider's attested enclave, with payments stopping the moment attestation lapses.Read the proposal
[ 08 ]FAQ
Questions buyers ask.
If you issue a payment stablecoin, a lot: reserves, disclosure, AML and capital rules. If you only accept or send stablecoins, mainly AML, sanctions and record-keeping duties. Our article on stablecoin compliance engineering goes into detail.
USDC on Solana or Base covers most payment use cases today, with low fees and broad support. We pick by your counterparties and ramps.
Yes. We build agent wallets with budgets, limits and payment protocols such as x402. See onchain AI agents.
