Anchorage opens Tempo custody with a pathUSD funding requirement

Anchorage Digital Bank, N.A. added Tempo custody on 15 October 2026, making four assets available to institutional clients: OUSD, USDT0, USDC.e and pathUSD. Support includes address creation, deposits and withdrawals through the bank’s segregated custody accounts and policy controls.[1]

The platform currently requires pathUSD for transaction fees. Additional fee assets may follow; general TIP-20 support is planned to shorten future token integrations.[1]

The platform’s fee choice is narrower than the network’s

Tempo has no native gas token. Its protocol accepts USD-denominated native TIP-20 stablecoins with sufficient liquidity in the Fee AMM. A transaction can select a fee token, and an account can set a default. That network capability does not mean a particular custodian has enabled every eligible asset.[2]

The distinction matters for treasury operations: a large payment balance and a usable fee balance are separate requirements. A process that funds only the payment asset can still leave an instruction unable to proceed through a platform whose fee token is different.[1]

The token name identifies a particular route

Tempo’s OUSD guide describes swaps as requiring liquidity and compatible transfer policies. It also explains that choosing a fee token changes what pays for the transaction; it does not convert the payment amount. A treasury team therefore needs to distinguish the asset delivered to its recipient from the asset spent on execution.[4]

The pathUSD documentation distinguishes production balances from faucet tokens on Tempo’s test network, even though the contract address is the same. Network identity is therefore part of asset verification: matching a ticker and address alone does not establish that an incoming balance is production money.[3]

Gas economics should be kept separate from custody pricing

Tempo specifies a dynamic base fee for a 50,000-gas transfer of about US$0.00003 at the floor and US$0.0006 at the cap. For 10,000 such transfers, those endpoints imply approximately US$0.30–US$6 in base fees. This illustration excludes priority fees, different gas use and Anchorage service charges.[2]

At that scale, a treasury implementation can be more constrained by approvals, correct asset selection and timely fee replenishment than by the illustrated base-gas amount. The custody addition addresses institutional access; operating the payment process still requires those balances and controls to be configured coherently.
