# Bridge Solvers
> [Alpha Preview] List the public solver wallets that pay bridge fills, per ecosystem.
**Alpha Preview** — Endpoints, response shape, and solver wallets may change
without notice.
`GET /api/2/bridge/solvers` returns the public solver wallets that pay fills.
Useful for labelling solver transactions on explorers, allowlisting
counterparties, or verifying that a destination-side fill really came from
Mobula's solver. No query parameters.

Per-solver fields:
* `ecosystem` — `evm`, `solana`, or `hl` (HyperLiquid L1).
* `address` — the wallet's public address in that ecosystem's format.
* `primary` — on EVM, the settler that owner-bound operations (settlement,
rebalancing, refunds) pin to; on Solana and HyperLiquid the single solver
wallet is always `primary`.
* `chainIds` — the bridge chain ids this wallet operates on, matching the ids
used by `/routes` and `/quote`.
## How the wallets are used
* **EVM** — deposits go to the bridge contract, never to these wallets. Fill
inventory also lives on the contract; any wallet in this pool can sign the
fill transaction, so destination-side fills originate from these addresses.
* **Solana** — the solver wallet holds the fill inventory (SOL + USDC)
directly, and SPL/SOL deposits built by `/quote` are memo-tagged transfers to
it.
* **HyperLiquid** — the solver's HyperCore account (same address as the EVM
primary settler); spot fills are paid from it and HL-origin deposits are
transfers to it.
Never send funds to these addresses outside the deposit instructions returned
by `/quote` — a raw transfer without the expected memo / calldata is not a
bridge deposit and will not be filled.
