Gemini no longer supports GALA(v1) for deposits, trading and withdrawals. If you’d like to trade or hold GALA on the Gemini exchange, it will need to be GALA(v2).

Before sending your GALA to Gemini, please ensure that it is not GALA(v1). Any deposits of GALA(v1) will not be accepted.

You can check if you have GALA(v2) by comparing it to the contract address here:

0xd1d2Eb1B1e90B638588728b4130137D262C87cae

If your GALA has this contract address, it is GALA(v1) and unsupported:
0x15D4c048F83bd7e37d49eA4C83a07267Ec4203dA
