Lending inside Serevin
Manage an underlying Morpho position through Serevin, with an explicit wallet review for each action.
In this chapter
Which lending network is connected?
Morpho is the general-purpose lending network listed in Robinhood Chain’s official ecosystem directory and the only external lending deployment currently reviewed in this application. Five reviewed USDG markets appear in the registry. That does not establish that no other lender exists.
Spark, Maple, Midas and Ethena assets can appear as collateral in those markets. They are not four additional lending engines integrated into Serevin. Uniswap, Rialto and Route provide trading or routing capabilities rather than the same lending service.
Serevin also has its own locally implemented isolated markets and funded term-credit contracts. They remain separate from Morpho and require their own release, funding and risk settings.
The direct lending flow
Manage market opens the native lending desk in Serevin. It prepares supply, withdrawal, collateral deposit, collateral withdrawal, borrowing, partial repayment and full debt-share repayment. An optional source link remains under market details for independent inspection.
The wallet calls the reviewed Morpho contract directly. Position ownership and output recipients are fixed to the connected wallet. Serevin does not receive custody or a broad delegation to manage the position. Each token allowance is limited to the required amount, with a zero reset if an existing allowance differs.
The deployment manifest pins the market’s five parameters, market identifier, Morpho runtime, token runtimes and precision, oracle and interest rate model. These are rechecked through the wallet provider before submission. Identity checks do not prove an oracle is economically sound, that a token cannot be frozen, or that liquidity will remain available.
What the transaction does and does not bound
The direct supply, borrow, withdrawal and partial-repayment calls specify an exact asset amount. Shares are calculated by Morpho at inclusion. These calls do not contain a minimum-share limit or an onchain deadline. The interface’s review expiry prevents a late wallet submission, but cannot stop a transaction already submitted from mining later.
Full repayment specifies the wallet’s current debt shares and an exact maximum token allowance chosen by the user. A changed debt-share position invalidates the review. Interest can change the cash needed; if the allowance is insufficient, the transaction reverts. Unused allowance can remain after settlement.
Borrowing and collateral withdrawals must pass Morpho’s health checks. Withdrawals also require available liquidity. A successful preflight simulation does not freeze those conditions. Failed final transactions can leave earlier token approvals in place.
Where Serevin fees can apply
These direct Morpho calls charge no Serevin fee. Underlying market interest, any Morpho market fee and network gas still apply. We have not invented or enabled a borrowing surcharge.
A separately reviewed borrowing router could deduct a disclosed origination fee from the borrowed amount. It would need capped fee terms, constrained authority, clear net proceeds and its own contract review. Users can bypass a Serevin interface fee by using the underlying lending protocol directly.
Existing Serevin contracts provide separate mechanisms for funded-credit fees, routed-swap fees and service membership. Production values remain unset. Neither trading volume, borrowed principal, LP liquidity nor user collateral is automatically protocol revenue.
