Following up on my earlier post, now from both sides: since Sept 19 we also run a provider (AXELAR), alongside our validator.
Two concrete things from the provider side I’d want in the migration design:
-
Claim costs. Our AXELAR provider submits around 100 relay-payment claims a day, for well under $1/day of rewards at current prices. That only works because claims are nearly free here. On a host chain where every claim pays gas, smaller specs and smaller providers stop being worth serving unless settlement is aggregated (batched claims or periodic settlement). I’d make that an explicit criterion when comparing destination chains.
-
Stake continuity. Provider self-stake is currently delegated to validators through dual staking, and validators are going away. Carrying bonded positions over 1:1, via a snapshot or direct conversion, would avoid pushing everyone through the same 21-day unbond at the same moment, which is exactly the sell wave nobody needs.
And one from the validator side: a defined wind-down with advance notice, at least a couple of reward cycles, so validator infrastructure can move to provider work in an orderly way rather than being switched off overnight.
Happy to share our claim and traffic numbers if they help with the cost comparison.
