 This can be solved by having a contract that provides an ERC-20 interface
 directly to the native token. To implement such a contract, the blockchain must

 # Proposed Solution
 
-Add one new blockchain parameter `TransferPrecompileAllowed` and a new precompile.
+Add one new blockchain parameter `TransferPrecompileAllowedCaller` and a new precompile.
 The parameter defines the address from which the precompile must be called.

 Precompile address: 0x0000000000000000000000000000000000000101 (directly after the `P256VERIFY` precompile from Fjord)

 The precompile can fail for the following reasons:

+* `TransferPrecompileAllowedCaller` is not configured for the blockchain

 * The `from` address has less than `value` native tokens
 * The input is not exactly 96 bytes long
 * The input parameters can't be parsed correctly

 # Open questions
-* Where is the right place for the `TransferPrecompileAllowed` configuration? Should it be part of `OptimismConfig`?
-* If `TransferPrecompileAllowed` is not configured, is it ok to have the precompile, although it will always revert? Or would it be better to remove it from the list of active precompiles?
