Most blockchains assume that where tokens live is where everything has to happen.
That assumption has a cost.
DRC-20 tokens exist on Dogecoin. Leave them there. What moves to BSV is the orderbook, the matching, the settlement proof, the permanent record of every trade.
The technical reason this works: inside every Dogecoin block, the transaction Merkle tree is identical to Bitcoin's. Double-SHA256, same structure, same proof-of-inclusion logic. A standard SPV library can verify that a specific DRC-20 transfer happened — without touching Dogecoin's proof-of-work layer at all.
Every trade generates a Merkle inclusion proof. That proof gets anchored to BSV via OP_RETURN - permanent, public, verifiable by anyone running an indexer.
On timing: token movement on Dogecoin takes ~2 minutes. That's Dogecoin's property. Everything on BSV side is immediate. Users see exactly where in the flow they are.
No bridges. No wrapped tokens. No custodians.
This extends to any UTXO chain with the same Merkle primitive. Each new chain is one adapter.
