Bridge

Doge Soft Bridge moves DRC-20 Coins between Dogecoin L1 and DogeOS. Outward is lock-and-mint; back is burn-and-release. Both sides are settled by DogeSoftBridge 2.6.0-ds-standard, a multi-attester contract on DogeOS, not a single hot-wallet approver. Every bridge inscription uses the Doge Soft Inscription Standard.

Deployment

DRC-20 uses 8 decimals on L1; wrapped coins use 18 decimals on DogeOS. Native DOGE is not bridged. Earlier Soft Bridge contracts are retired.

Deposit: Dogecoin → DogeOS

1. Get a ref. The bridge issues ref = keccak256(abi.encode(keccak256("DOGEOS_EVM"), recipient, nonce)). The ref is a fingerprint of your DogeOS address, and its signed record is public at GET /ds/ref/<ref>.
2. Inscribe. Send a normal DRC-20 transfer to custody with the ds tag: {"p":"drc-20","op":"transfer","tick":"DU$T","amt":"1000","ds":{"action":"BRIDGE_L1_DEPOSIT","ref":"0x…"}}
3. Verify. Doge Soft's indexer waits for 6 confirmations and checks that the sender really held the DU$T, so a false inscription can't get through.
4. Attest. At least 2 of 3 registered attesters sign the mint digest, which covers the ref and nonce.
5. Mint. mintFromL1Tx rebuilds the ref from the recipient and nonce, refuses a mismatch, and refuses a ref that was already used. wDU$T can only go to the address the ref was made for.

Withdraw: DogeOS → Dogecoin

1. Burn. Call burnForRelease on the wrapped token with your Dogecoin address. The contract issues a request id.
2. Release. Custody inscribes a DRC-20 transfer back to you tagged BRIDGE_L1_RELEASE, with ref = the request id.
3. Settle. After 6 L1 confirmations, 2 of 3 attesters sign and settleRelease closes the request on chain. Each request id settles once.

Bridge verbs

Verb	Where
BRIDGE_L1_DEPOSIT	User's DRC-20 transfer to custody. ref = recipient fingerprint.
BRIDGE_L1_RELEASE	Custody's DRC-20 transfer back to the user. ref = request id.
BRIDGE_L2_INTENT	Intent record issued by Doge Soft services.

Safety rails

• Single-use refs for deposits and releases.
• 2-of-3 attesters; one key can't mint or settle. The threshold and attester set are public: attesterThreshold(), getAttesters().
• Timelocked admin actions and a pause switch.
• Reserve cap: 1,000,000 DU$T total minted. A stale reserve attestation (older than 7 days) pauses new mints; it never puts funds at risk.
• Per-transfer limits: min 1, max 10,000,000.
