This script can be used to migrate old AE (ERC-20) tokens from Ethereum to aeternity mainnet if you know the method params.

Source Code

How to use

Set environment variables (dependent on the entrypoint to call)

SECRET_KEY=<your secret/private key> // only required for the migrate entrypoint

ENTRYPOINT=<balance | root_hash | migrations_count | is_migrated | contained_in_merkle_tree | migrate>

ETH_ADDRESS=<the ETH address to check or migrate> // needs to be upper-case

AE_ADDRESS=<the AE address that should receive the tokens>

LEAF_INDEX=<the index of the leaf in the merkle tree, needed to calculate the root_hash>

SIBLINGS=<the siblings of the leaf, needed to calculate the root_hash>

SIGNATURE=<the ETH signature that signed the message containing the AE address>

Note

The SIBLINGS can be defined like this ...

SIBLINGS='["051BDA22F68DA9DF313AF7CECC674719144C0F8ECA3FAB3198D7142B9CEAAC26","0CAB2FB45014E7525AEE712958160543F6FD72F5240190FC3DD8D81DE8C50273","06C6A716161F47FAB561CBB8396780248730967D7A29BB168C07FEF3A4D350E3","8E50602C4E28386DEACF5E13B6E6A61A6DFAE36B9E173DB7A049303EC2E53DB3","1B4D4F067BAFCD1FCCB4460AC31A05EED48563E7045DC4EF996E7D8C3EEB9EFD","3BB0582BD65EA4C994CB9391533B782A7136FB711B47C512556A97313C973F26","F884BF2270FACB34FD0A7C49092B102DFB2E43C42D3D38B44E394D9A258AEE93","19DA2DF18294D5E3E264AEBB48DA4D3622457BDD1162C7416198C732978DC210","D2888B644AE539E259B2D104214239F30B810ADE99874B5EFE68A0FD77CBC1A5","AD206ED34B49DA709CF01A84D53489D7908D78952181E9E61C536799189FE411","2FF75575202A4A1D4DF8F0888967A9E9ABEB3C364FFF1C9E9D51A946C7AD30F3","58517514D61EA90D01AA0A8547BA02D98D393DE25A615FAB868828DF88CF6769","AEEAFA5E07BB461264A856B13C3C346DFCD870EE48C1D4CE40A69DA720A8E2BD","764CEF512A9223E21BD5650B55245188876A83B15BB5B3B418B87E28F1B74FB9","7195B9E30E43FA2F188D69C5F61BB75A00CF639E7925CAF4C1FD2AF32D976B0B"]'

... and obtained by calling the API of the current token-migration backend in the following order:

  1. https://token-migration.aeternity.io/info/0x932Cf9910672B8a26BD31141Ff8f11e9b7dfa6e2 (providing the ETH address)
    • response:

    "tokens": "349185165700000000000",
    "migrated": false,
    "migrateTxHash": ""
}
    • this address has been migrated using this snippet and thus it is not marked as migrated in the backend
    • if you call the is_migrated entrypoint of the contract by providing the address in upper-case you will see that the address has been migrated successfully
  2. https://token-migration.aeternity.io/siblings/12183 (providing the leaf index)
