Proving Bitcoin without moving Bitcoin.
A Creditcoin contract verifies that a Bitcoin UTXO exists and holds a given amount — no wrapping, no bridge, no custodian. Every figure below is read live from a public endpoint when this page loads. Nothing here is pre-recorded, and nothing is filled in when a request fails.
Creditcoin and the proof-gen API run as a local devnet on the author's machine, not a public network, because exSat is not a registered Attestcoin source chain on the public network. 127.0.0.1 only resolves in a browser on that same host. To reach them from a hosted copy of this page, tunnel the two ports (cloudflared, ngrok) and paste the public URLs here. EOS and exSat are public and need no tunnel.
WHAT exSAT CURRENTLY KNOWS
exSat's Bitcoin index has stopped advancing — a boundary on what can be proven, not a pipeline failure.

Four hops, and only the first one involves Bitcoin itself.
CHECK ANY UTXO YOURSELF
Reads exSat's index on EOS mainnet directly — public data, works with no access to ours.
WHAT HAS ACTUALLY BEEN RELAYED
Every relay this project has ever made, read live from the receiver contract's logs on exSat EVM.

WHAT THE PROOF IS FOR
Wrapped Bitcoin does get reserve feeds today — but a feed is an assertion: an oracle committee reads a Bitcoin node off chain and signs a number the contract cannot check. Here the reserve arrives as a proof the contract verifies itself, and the mint refuses to execute when it does not hold.

One fact, followed across four chains. Each station is a separate request; the link on each one opens an explorer we do not control, so the same hash can be checked elsewhere.
