About the ETH-ETC AMB
ETH-ETC Arbitrary Message Bridge information
An Arbitrary Message Bridge (AMB) between the Ethereum Mainnet and the Ethereum Classic extends the number of the applications that can leverage cross-chain communications. It was mainly deployed as an experiment to migrate the vanilla TokenBridge serving exchange ETC to WETC to the AMB protocol.
Any application can build its own AMB extension. This is represented by two mediator contracts so that either assets or arbitrary data can be transferred between chains. The deployed mediator contracts do not require a set of oracles to be setup, allowing an application to launch quickly and reducing the cost of application ownership.
The mediator contracts rely on the following information about the ETH-ETC Arbitrary Message Bridge:
Ethereum Mainnet:
AMB contract:
0x5a91B345244d3A285b30287b4c63c154eCBD2b7e
Gas limit to call method in the xDai chain:
2000000
Finalization rate:
8
blocks
Ethereum Classic:
AMB contract:
0xA126c73d1bDf3a3D5F719A8D38a4692186e7503F
Gas limit to call method in the Ethereum Mainnet:
2000000
Finalization rate:
8
block
It is possible to get an AMB transaction status by using the Live Monitoring app: https://alm-etc.herokuapp.com/.
