Brionic Payments
Set up a trust line on your own wallet
To hold an issued token like RLUSD on the XRP Ledger or USDC on Stellar, your wallet needs a one-time trust line to the issuer. This tool builds it for your own cold or self-custody wallet, you approve it in your wallet, and your keys never touch Brionic.
Three steps, keys stay with you
1 · Pick a token
Choose RLUSD, USDC, or paste any issuer. We look up the details and build the exact trust line transaction.
2 · Scan or open
Scan the QR with your wallet, or open the link on your phone. Cold wallet? Copy the raw transaction into your signer.
3 · Approve
Your wallet asks you to sign a one-time trust-line op. Approve it, Brionic never sees your seed or private key.
About trust lines
Only for issued tokens
Native XRP and XLM need no trust line. You only need one to hold issued tokens like RLUSD (XRPL) or USDC (Stellar).
A small, refundable reserve
Each trust line locks a tiny base reserve, about 0.2 XRP on the XRP Ledger or 0.5 XLM on Stellar. You get it back if you remove the trust line later.
Verify the issuer
A trust line authorizes one specific issuer. Always confirm the issuer address so you don’t trust a look-alike token. Our presets use the official mainnet issuers.
Non-custodial by design
We generate an unsigned transaction. Signing and broadcasting happen entirely in your wallet, the same way Brionic settles payments straight to merchants.
