Stargate is the bridge built on pooled liquidity rather than wrapped promises: a transfer leaves one chain as a deposit into Stargate's pool there and arrives on the other as a payout from Stargate's pool on that side, settled over LayerZero's messaging with the same asset on both ends. Its second generation holds those pools on dozens of chains and extends them with Hydra, minting a native representation where no pool exists yet.

The pools are the product. Every transfer is credit moving between them, and the providers who deposit into a pool hold an LP token that claims one unit of the pool's asset and earns the fees transfers pay. A pool that is short of its asset charges more to leave and rewards transfers that refill it, so the fee curve is a live signal of where liquidity is needed, and the credit a pool holds toward each destination bounds how much can cross at once.

That makes every move here a timing question. The fee on a transfer depends on the deficit at the block it fires; the right moment to deposit is when the pool is short and paying for it; a redemption can only take what the pool holds locally, and that number moves with every transfer in flight. Doing any of it by hand means quoting, waiting, re-quoting, and signing at whatever moment a person happens to be looking, with the message fee estimated off chain and padded against the chance it moved.

In a plug every one of those figures is read on chain in the same transaction that acts on it. A cross-chain send quotes the pool's fee curve and the LayerZero message in place, sets its minimum to exactly what the quote says arrives, and pays exactly the quoted message fee, so it delivers what was quoted or does not run. Deposits and redemptions fire against the pool's own numbers, gated by whatever condition matters: the redeemable amount covering the whole position, the pool balance falling below its liabilities, a balance landing in the wallet.

Proceeds swept to the chain where they are spent the moment they arrive. Liquidity added when the pool pays for it and pulled when the pool can cover it. Transfers that never overpay a padded fee and never land short of their quote.

Bridging is a market like any other, and the transfers that price best are the ones that fire on the pool's numbers rather than on someone's schedule.
