ERC-8004 Agents on Mantle Mainnet

Mantle is an OP Stack L2 that swaps Ethereum calldata for EigenDA, which is why fees stay low even when the network is busy. For agents running validation pipelines or emitting feedback at volume, that fee structure adds up fast on other chains. Gaming studios and consumer app developers have gravitated here partly for that reason — the economics of per-feedback writes work out differently than on Ethereum or even Base. One real limitation: the cross-chain bridge surface is narrower, so moving assets in and out takes more planning than it does from Base.
