The Same Bridge, the Parity Way — and the Bill
We rebuilt our trustless bridge with the stack that runs Polkadot↔Kusama: pallet-bridge-grandpa plus ordered message lanes. Same trust model, different machinery — and this time every proof lands as a signed transaction with a fee on the record. The head-to-head, measured.
ISMP Bridging with Satsuma
We ran two independent satsuma chains — different genesis, different validators — and moved value between them with no multisig, no custodian, no middleman. Each chain verifies the other's GRANDPA finality on-chain, then verifies a state proof. 4 seconds end to end.
