 ### Bug Fixes
 
+* (app) [\#749](https://github.com/cosmos/ethermint/issues/749) Fix panic in `AnteHandler` when gas price larger than 100000
 * (rpc) [\#305](https://github.com/cosmos/ethermint/issues/305) Update `eth_getTransactionCount` to check for account existence before getting sequence and return 0 as the nonce if it doesn't exist.
 * (`x/evm`) [\#319](https://github.com/cosmos/ethermint/pull/319) Fix `SetBlockHash` that was setting the incorrect height during `BeginBlock`.
 * (`x/evm`) [\#176](https://github.com/cosmos/ethermint/issues/176) Updated Web3 transaction hash from using RLP hash. Now all transaction hashes exposed are amino hashes:
