Move BTC. Keep the proof.
Deposit native BTC and receive foonBTC where you need it; burn foonBTC and receive native BTC back at your own keys. The devnet rail is live end-to-end today — deposits prove, mints verify, tested against real mainnet Bitcoin blocks. Mainnet opens the moment custody is a published Conclave 3-of-5 descriptor, and not a moment before.
The whole triangle already verifies — for free.
Before a single sat is custodied, the full BTC ↔ Base ↔ Solana proof pipeline runs live on the Taifoon devnet, fed real mainnet data. Reading mainnet is free and devnet gas is free, so this costs nothing — and it proves the exact machinery that custody will back. It verifies value; it does not move value. Custody-backed mint stays gated to genesis, on purpose.
What each opret anchor actually says.
OP_RETURN anchors carry real protocol payloads — RGB commitments, OpenTimestamps proofs, Counterparty ops. When the spinner decoder is active, the decoded fields appear here directly. When it is not yet active, the panel says so honestly rather than guessing.
Opret anchors only — OP_RETURN outputs where the decoder can read what the payload actually says. The decoded fields come directly from the spinner decoder; when absent, the row says so rather than guessing.

Permissionless Bitcoin — completed with proofs.
Bringing Bitcoin's liquidity to other ecosystems without a custodial wrapper is the right mission — zBTC proved the demand for it on Solana, and its final technical act (SPV proofs on Solana) pointed at the right answer. foonBTC finishes that thesis: the proof is not a feature bolted onto the bridge — the proof IS the mint authority. No permission asked, none needed: anyone with BTC and a proof can mint; anyone with foonBTC can burn back to native keys.
Read. Verify. Act.
foonBTC is the top floor of one coherent Bitcoin layer — each floor stands alone, each is stronger for the ones beneath it.
Bitcoin carries more than transfers: RGB assets, Omni, Counterparty, timestamps — all living in anchors and OP_RETURN payloads ordinary explorers can’t read. Taifoon indexes every header and decodes every anchor into what it actually says. Bitcoin, decoded — not just observed.
RGB observatory →Every decoded fact carries a 6-layer V5 inclusion proof against one superroot — header, twig, transaction, finality. You don’t take our word for a single byte; you check it, or your software does.
Proof explorer →Native BTC that moves: deposit on Bitcoin, a proof from floor 02 mints foonBTC on the landing chain; burn, and the council releases native BTC to your keys. Acting on Bitcoin becomes as verifiable as reading it — the bridge above is this floor.
The first Bitcoin an agent can actually use.
Autonomous agents need verifiable information about the blockchain world before they can safely transact — Taifoon is the verification and coordination layer that gives them a universal, trust-minimized view of on-chain reality. Bitcoin is where that matters most and works worst: an agent cannot KYC with a custodian, cannot trust an announcement, cannot eyeball a reserves dashboard.
Decoded anchors, reserve states, and headers over plain HTTP — every response machine-parseable, every fact carrying its proof path.
Deposit and redeem are open interfaces gated by proofs, not accounts. An agent holds native BTC exposure with no counterparty relationship to us.
The V5 blob verifies against on-chain verifier contracts — an agent checks its own money and its own facts, no oracle subscription required.
Every claim has an address.
Deployed on the Taifoon devnet (chain 36927) and tested against real Bitcoin mainnet blocks; these contracts are the mainnet candidates. The read plane behind them — Bitcoin header index, RGB anchor observatory, V5 proofs — runs in production today.
Four things foonBTC will never do.
Mainnet stays closed until custody is a published Conclave 3-of-5 descriptor.
No proof, no mint — including for us. The operator path does not exist.
foonBTC promises no yield. Ever. Integrations would be named, opt-in, risk-labeled.
Devnet says devnet. Statuses change when reality does.
