When you deposit
into a
Morpho vault, you hold vault shares in its place. Each share is worth a little more
every block as the vault earns interest. Withdrawing turns them back: the vault burns your shares and sends you the
they are worth, interest included. There is no lockup and Morpho charges nothing to leave.
No approval is needed. The vault burns your shares directly.
The plug does one thing on Base: it
withdraws all of your
from Gauntlet USDC Prime. "All" is worked out when the run lands, not when you open the plug, so it takes every bit of interest earned up to that block and leaves no shares behind.
To take out part of it, change "all" to an amount. To leave a different vault, swap it for any other ERC-4626 vault on Base that holds
. The plug reads the wallet that runs it, so it works for whoever opens it.
We simulated the plug on Base in November 2026 as a wallet holding Gauntlet USDC Prime shares, and it withdrew the whole position in one run. At that block 100
was worth 89.30 shares.
Morpho charges nothing to withdraw, and Gauntlet USDC Prime's performance fee was zero. The vault was paying 4.50 percent a year when this was written, which you stop earning once you leave. Gas for the run was about a million, about a cent at Base's gas prices.
