Read-only router state. All views work on read-only clients.

fallbackSwapRouter

fallbackSwapRouter(): Promise<Address>

The Uniswap fallback "venue" address — dynamic router configuration, which is why it isn't in the static PAMMS mapping.

const fallback = await router.fallbackSwapRouter();

Returns Address

fallbackQuoter(): Promise<Address>

The quoter contract used to price the fallback route.

Returns Address

fallbackFee(): Promise<number>

The global fallback fee tier, in hundredths of a bip (e.g. 3000 = 0.30%).

Returns number

getPairFee(tokenA: Address, tokenB: Address): Promise<number>

The raw per-pair fee tier override — 0 means unset. Order-independent: getPairFee(a, b) === getPairFee(b, a).

await router.getPairFee(USDC, WETH);

Returns number

resolvedFee(tokenIn: Address, tokenOut: Address): Promise<number>

The effective Uniswap V3 tier for a pair: the per-pair override if set, otherwise the global fallbackFee.

Returns number

isWhitelistedVenue(venue: Address): Promise<boolean>

Whether an address is a whitelisted pAMM. The Uniswap fallback is usable as a venue without being whitelisted, so this returns false for it.

Returns boolean

getWhitelistedVenues(): Promise<Address[]>

Every whitelisted pAMM venue (excludes the Uniswap fallback). Order is not guaranteed.

const venues = await router.getWhitelistedVenues();

Returns Address[]

paused(): Promise<boolean>

Whether swaps are paused. Quote functions remain callable while paused.

Returns boolean
