Sentinel is core infrastructure for developers: point your app at it and ship a compliant on-chain product — tokenize and settle on XRPL and TX with fail-closed compliance enforced before anything moves. It holds no keys; your users keep their own custody. There is no Sentinel vault to hack, freeze, or lose. Fifty50 is our own product built entirely on it — the prime example of what you can ship.
Tokenize real-world assets on XRPL (MPTs) and TX/Coreum (native Smart Tokens).
Settle all-or-nothing across both ledgers, compliance enforced before any asset moves.
Holds no keys. The client signs; Sentinel verifies, relays, and records — bring-your-own-custody.
Four steps to a compliant on-chain product — your app never holds a key and never becomes the compliance engine itself:
POST /sentinel/api/v1/assets/register binds your asset to your tenant on XRPL or TX.POST /sentinel/api/v1/execute-settlement clears compliance for both parties, then settles all-or-nothing on-chain.The API is permissioned — every call is ed25519-signed by a registered tenant. Public, unauthenticated endpoint:
GET /sentinel/healthPOST /sentinel/api/v1/…Fifty50 is our own live product, built entirely on Sentinel: it computes a fair equity split and tokenizes it with a single Sentinel call — the split becomes a real on-chain asset with fail-closed compliance attached. Anything you build can do the same.
Around Sentinel sits a stack of audited, composable building blocks — transfer & a live cap table (Conduit), liquidity (Reservoir), agent reputation (Aegis), underwriting & coverage (Backstop), a compliance rule-pack marketplace (Lexicon), cross-ledger bridging (Causeway), plus credentials, credit, governance, baskets, pricing and dispute resolution. Compose what you need.
