How reserves appear in your balances
Your total balance is split into an available amount, any reserves, and any holds. A reserve is part of the balance that a network requires the account to keep, or that we set aside to cover future fees. It isn’t a hold: holds are temporary and tied to a specific operation, like a pending withdrawal. Available balance is already net of both.
For every line item that can appear under an asset, see Reading balances.
Reserves are denominated in the network’s native asset. A USDC balance on Solana carries no reserve of its own, but the rent for its token account is charged in SOL.
Every reserve amount is set either by the network or by us to cover estimated fees, and any of them can change. Treat the figures on this page as a guide—the reserve lines in your balance always show the current amount.
Types of requirement
The first two are protocol rules. The operational reserve is ours: without it, a wallet could stake its entire balance and have no gas left to unstake. It applies only while a wallet has an active stake.
Some account or storage reserves are a flat minimum balance; others, like Solana’s rent, scale with how many accounts you have rather than how much you hold, so a wallet with three stake accounts owes three deposits. A trustline, which you’ll see called an allowed asset in the web dashboard, consumes part of the account reserve as well.
Accounts that must stay funded
We create trustlines automatically for every enabled asset and fund the reserve they require from an Anchorage Digital bootstrap account, so a new wallet is ready to receive without setup and without you paying the trustline reserve yourself. Soroban tokens on Stellar need no trustline. To allowlist a newer Stellar asset on an existing wallet yourself, see Stellar asset allowlisting.
The XRP Ledger base reserve is read live from the network, so it tracks network changes rather than a hardcoded figure. On Polkadot, an account that drops below the existential deposit is reaped and its balance destroyed, so we withhold the deposit and no operation can trigger it.
Solana and Fogo rent is read live from the network rather than hardcoded, and token accounts are created as needed. Their rent reserve reduces your withdrawable balance, not just your stakeable balance. Solana is gradually reducing rent across the board, so we don’t publish fixed figures here—check the Rent Reserve lines in your balance for the current amounts.
Reserves held for staking
While you’re staked, we hold back a small amount of the native asset as a Staking Reserve, so you always have enough to pay the gas for a future unstake or claim. This applies on Sui, Aptos, Movement, Starknet, Oasis, Sei, and Cosmos and IBC chains. The reserve is released once the position is fully withdrawn. On Filecoin, an Auto-claim Reserve is held while you hold vesting positions. It covers fees on vesting claims and on scheduled claim transactions from auto-claim and stake, rather than an unstake. Each reserve is sized to the estimated fee for that network, so the amount varies by network and can change as fees do. Your balance always shows the current figure.Leave the reserve unstaked. If you try to stake your full balance, the reserve is deducted first, so the amount that actually gets delegated is lower than the amount you entered.
Activation fees
Activation fees aren’t reserves—nothing is held back from your balance. They’re one-time network charges added to a transfer when the destination doesn’t exist yet on that network. We cover them here because, like reserves, they mean the amount you spend differs from the amount that lands.
The sender pays the activation fee, not the recipient, and every charge here is included in the fee estimate before you sign. On HyperCore the amount is quoted by the network and booked separately as activation gas, so your deposit and the fee aren’t conflated, and Anchorage Digital covers it on your behalf. NEAR validates every transfer against worst-case cost, so its charge applies whether or not the recipient already exists.
Budget for the extra TRX on first-time Tron destinations, and again on any transfer that uses a memo, which most exchange deposits require.
