Most DeFi yield products pool everyone’s money into one big pot. One hack drains everyone. Blend gives every user their own Gnosis Safe instead. Blend is a non-custodial Yield Coordination Engine built on the Separately Managed Account (SMA) model. Your neobank uses it to offer savings products. Your users get isolated custody and DeFi yield without touching a smart contract.Documentation Index

Pooled vaults vs. Blend
| Pooled vaults (most apps) | Blend’s SMA model | |
|---|---|---|
| How funds are held | Everyone’s money in one pool | Each user gets their own Safe |
| What a hack means | Entire pool drained. Everyone loses. | Only the affected Safe is at risk. An attacker would need to break into thousands of Safes one by one. |
| Can you customize? | No. Everyone gets the same returns. | Yes. Your neobank offers different account types with different allocations. |
| Who controls the money | Often the platform or its admins | The user. They are the only signer on their Safe. |
| What strategies are possible | Usually just lending for a basic APY | Advanced options like hedged positions, multi-chain execution, and multi-currency products |
| What happens if the platform disappears | Users may lose access | Users keep full access. The Safe is a real smart-contract wallet on-chain. |
Think of pooled vaults like a savings account where you and a thousand strangers share one bank vault. Blend is more like having your own vault at the bank. Same bank, but only you have the key.
How it works
- Your neobank creates account types (e.g. “Savings”, “Growth”, “BTC+”) and picks which vaults to include.
- A user signs up and Blend deploys a Safe just for them. They are the sole signer.
- The user deposits through your app. Capital routes to vaults scored by Philidor.
- Yield accrues in the user’s Safe. Rebalancing happens automatically. The user can withdraw at any time.
Philidor risk scoring
Blend uses Philidor, an institutional-grade risk scoring system, to evaluate every vault in the catalog. Each vault receives a composite score (0-10) across three dimensions: asset quality, platform security, and governance controls. Vaults are classified as Prime (8-10), Core (5-7.9), or Edge (0-4.9).
| Tier | Score | What it means |
|---|---|---|
| Prime | 8 - 10 | Top-tier protocols with strong audits, high TVL, and proven governance |
| Core | 5 - 7.9 | Established protocols with solid security and moderate risk |
| Edge | 0 - 4.9 | Newer or higher-risk protocols. Higher potential yield, more exposure. |
Where yield comes from
Blend connects to audited DeFi protocols across lending, staking, and fixed income.| Yield Source | Category | Description |
|---|---|---|
| Morpho Blue | Lending | Leveraged lending positions and delta-neutral strategies |
| Aave V3 | Lending | Money market supply-side yield |
| Euler | Lending | Flexible interest rate lending vaults |
| Euler Earn | Aggregation | Aggregated yield across multiple Euler vaults |
| Pendle | Fixed income | Fixed-term yield from tokenized treasury positions and yield markets |
| Merkl | Incentives | Liquidity mining rewards and protocol incentives |
| Staked BTC | Staking | Bitcoin staking yield from Botanix and other BTC protocols |
| ERC-4626 Vaults | Standard | Any tokenized vault following the ERC-4626 standard |
| Spot Assets | Spot | Tradeable assets with price feeds for yield-bearing positions |
| Receipt Tokens | Protocol | Protocol receipt tokens representing yield-generating deposits |
What you control
As a neobank, you control the user experience and the risk profile:- Vault catalog. Browse Philidor-scored vaults and request the ones you want.
- Account types. Create products with specific vault allocations and risk profiles.
- Flow plans. Approve or auto-approve rebalancing operations before they execute.
- Credentials. Manage API keys and signing keys for your integration.
- Pause. Stop new deposits on your account types at any time. Withdrawals always work.
What are flash loans?
What are flash loans?
Flash loans let the system borrow a large amount and pay it back within the same transaction. This happens in a single block. Strategies use flash loans to set up hedged positions without putting user money at extra risk. If any step fails, the entire transaction reverts and nothing happens. The user’s funds stay exactly where they were.
