The thesis

The Rune lives on Bitcoin. Its market lives on Robinhood Chain. Every wrapped token is backed by a Rune held in a published reserve, and nothing trades until that reserve is proven.

Native = the Rune on BitcoinWrapped = the ERC-20 on Robinhood Chain
Built to these numbers
1:1

Backed supply

Wrapped totalSupply never exceeds the canonical Rune supply held in custody, reconciled at every finalized checkpoint.

1.00%

Per-trade fee

0.25% to the creator, 0.25% to the protocol, 0.50% to holder rewards. Charged on buys and sells.

0.115BTC

Graduation threshold

A deterministic target, set per market in WETH using a fresh BTC/ETH oracle price. At the line the curve completes and migrates to a DEX pool.

Two chains.One asset.

Bitcoin holds the truth. Robinhood Chain holds the market. Each side does only what it is good at, and the line between them is drawn on purpose.

Every launch walks the same nine states, and every state shows its proof. No trading against unbacked supply.

Creator fills the launch

Ticker, description, logo, links, initial supply and an optional dev-buy amount.

Etch and inscribe

Name eligibility is checked under Runes rules. Etching and inscription transactions are built.

BTC_BROADCAST

Sent to Bitcoin

The inscription commits the CREATE2 address of the future ERC-20, so identity is fixed before deploy.

BTC_CONFIRMED

Confirmations reached

The watcher waits for the required depth and indexes the Rune ID and exact balances.

Full canonical supply sits in published reserve UTXOs. The reserve dashboard goes live.

The matching ERC-20 activates with circulating plus escrowed supply equal to the reserve.

Dev buy, then public

The creator buy runs first, atomically, in the same transaction that opens the curve.

DEX_ACTIVE

Pool open, LP locked

Wrapped Rune / WETH trades on an audited DEX. LP rights are locked, with receipts on chain.

Bonding curve

Priced inWETH.Quotedin BTC.

A constant-product curve with virtual and real reserves kept apart. Sells pay only from real ETH. The BTC figure is a quote from an oracle, never the settlement asset.

Two chains means two sets of failure modes. These are the ones the contracts, bridge and indexer are tested for before anything holds value.

Reorg

BTC

A Bitcoin reorg erases the deposit a mint was based on.

FIXConfirmation depth, reconciliation jobs and a REORG_REVIEW state.

BRIDGE

One Rune deposit is claimed twice, or a message is replayed from another chain.

FIXUnique deposit addresses, nonces and proofs accepted exactly once.

A bot wraps your trade to move the price against you.

ORACLE

An old BTC/ETH price sets the wrong graduation line or quote.

FIXHeartbeat, decimals, sequencer and outlier checks in the OracleAdapter.

A sell is paid out of virtual reserves that were never deposited.

FIXSells settle from real ETH only, with solvency invariant fuzz tests.

CUSTODY

Custody keys leak and the reserve can be moved.

Open the RuneCurve shell and the core is Bitcoin. Custody addresses, UTXOs, Rune ID, supply and outstanding liabilities are published, so anyone can reconcile them.

A contract event alone is not a Bitcoin reserve proof. The page links to the Bitcoin transactions and the Robinhood Chain mint and burn events.

Bothdirections.

Bring a Rune in from Bitcoin, or burn the wrapped token and take the Rune home. Retries are idempotent and every leg publishes its transaction ID.

Security model

Dual-chain custody verification. The bridge uses a threshold multisig, publicly verifiable reserves, and timelocked withdrawals, with cryptographic proofs published for every transaction.

Where each trade's fee goes

Proposed defaults, configurable per market. Rewards go out every 4 hours to up to 100 eligible holders by time-weighted balance, in WETH until a vetted BTC-backed token and route exist on Robinhood Chain.
