BSA Gate
Live on Ethereum Sepolia

Who may pay. Whether it’s safe.

BSA Gate is a checkpoint for stablecoin payments. Before any USDC settles, one gate checks the payer’s on-chain permission with ENSv2 and screens the payment with Intercepta, then settles over x402. The same gate protects online stores and autonomous AI agents.

Test the live gate yourself

You play the shopper. Give yourself an identity, take it to a checkout, and watch the gate decide. Steps 1 and 2 are free (no USDC). Paying for real is optional.

1

Get verified

Connect your wallet, pick your traits (over 18, country). The issuer mints you a <handle>.bsagate.eth identity. Only the issuer can write those attestations, so you cannot fake them.

Get verified
2

Check out

Bring that identity to a gated checkout. “Check eligibility” runs the real ENS and Intercepta checks for free. Change what the merchant requires and watch it pass or block, with the reason.

Watch the feed

Every attempt, settled or blocked, shows up in the live activity feed below with the exact reason it passed or failed.

Want to go further? The agent console lets you delegate a spend-capped, revocable AI agent to your identity, so it can pay on your behalf within limits you set.

How it works

One gate, four checks

Every payment, from a shopper or an AI agent, runs the same four checks. It settles only if all four pass; otherwise it stops at the first failure and returns a clear reason. No money moves on a block.

Who it’s for

Two sides of one gate

Shoppers & AI agents

Get verified once and pay anywhere that trusts BSA Gate. Your identity is portable and only the issuer can write it. Delegate an AI agent that inherits your identity, spends within a cap you set, and can be revoked on-chain at any time.

Get verifiedAgent console

Merchants & stores

Add a “Pay with USDC” method where every payment arrives already checked: the payer proved who they are, and Intercepta screened the transaction. Set the required attestations per product, so one item can require 18+ and another a jurisdiction.
