Fluid V4 Brings Automated Lending Infrastructure to Cardano DeFi

FluidTokens said Fluid V4 is almost ready for release in July, with an audit already completed and mainnet launch next. The announcement was amplified by Charles Hoskinson, who praised the team’s progress and said Fluid continues to impress him.

The update arrives as Cardano DeFi is moving through a more product-heavy phase, with new stablecoin testing, Bitcoin-related liquidity work and lending protocols competing to make on-chain capital more usable. Cardano’s official app directory describes FluidTokens as a Cardano-Bitcoin lending and borrowing protocol covering lending, borrowing, staking, sponsored transactions, rental positions and boosted-stake products.

FluidTokens V4 Upgrades Cardano Lending Markets

FluidTokens is a non-custodial DeFi platform built around lending, borrowing, liquidity pools, P2P loans, NFT renting, boosted stake and transaction automation on Cardano. Its documentation says users can provide liquidity through Multi Pool Lending, define borrowing conditions, set interest, choose accepted collateral and control who can borrow from a pool.

The project’s website describes its Cardano product line as a DeFi platform with lending, borrowing, staking, renting and boosted stake features. It also lists liquidity pools as a way to create instant loan markets and earn APR across token pairs, with TVL shown at about $4.4 million.

V4 expands that model from a lending app into a more configurable loan infrastructure layer. The public FluidTokens Lending V4 repository lists support for static and dynamic lending pools, multisig support for institutions and large liquidity providers, borrowing from multiple pools in the same transaction, installments, grace periods, late repayment penalties, refinancing and permissioned pools.

That changes the product from simple lend-and-borrow flows into a market where pool owners can define more precise rules for capital, collateral, repayment and access. For $FLDT, the release gives the ecosystem a clearer connection between token utility, governance and active lending infrastructure.

Automatic Liquidations Add Stronger Risk Controls

Automatic liquidations are the largest risk-management feature in Fluid V4. In lending markets, liquidation rules define how a protocol handles loans when collateral conditions weaken or repayment terms are not met. Fluid’s V4 repository lists four liquidation types, including oracle-based liquidation models and Dutch auction handling for collateral.

The same repository states that lenders can enable automatic loan liquidations and optional automatic principal compounding. Bots compete to execute those transactions and earn liquidation or compounding fees set by the lender.

That gives Cardano lending pools a more automated operating model. Instead of relying only on manual tracking, a pool can be configured so unhealthy loans are detected, liquidated and, when enabled, converted back into principal.

Repayments, collateral handling and compounding can then move through manager scripts designed for lender control.

Automatic compounding also reduces idle capital inside lending pools. When repayments or liquidated value return to the lender manager script, bots can compound available principal back into the pool and take a fee for execution. The lender still retains manual withdrawal rights over assets and bonds connected to the manager script.

Secondary Loan Markets Create Exit Liquidity for Lenders

Fluid V4 also adds a secondary loan market function. The repository states that lenders can sell their positions to compatible pools to receive liquidity back when needed. It also states that borrowers can be locked so they cannot transfer their loan position to another user.

That feature addresses one of the practical limitations of lending markets. When capital is deployed into an active loan, the lender may not want to wait until repayment or maturity to regain liquidity. A secondary loan market gives the lender a potential exit route if another compatible pool can absorb the position under matching conditions.

Non-transferable borrower positions add a separate control layer. In permissioned pools, KYC-token structures or institutionally configured lending environments, a lender may need clearer limits around who can hold a borrower position. Fluid V4’s borrower lock design gives the protocol a way to keep certain loans attached to the original borrower rather than allowing unrestricted transfer.

The repository currently shows no published release, so V4 should be treated as a near-mainnet upgrade until the production rollout is completed. Once live, the operational difference will be specific: FluidTokens lending pools on Cardano will be able to combine custom pool rules, automated liquidation handling, compounding, secondary lender exits and locked borrower positions inside one contract architecture. For Cardano DeFi and the $FLDT ecosystem, that moves lending closer to a managed capital market instead of a set of isolated borrowing positions.
