Excellent use of IRIS:

1. Post wstETH as collateral
2. Borrow USDC at 4.85%, fixed for 90 days
3. Put the USDC into a Pendle PT
4. Redeem the PT at expiry and roll it again before the loan matures

The rate on step 2 doesn’t change until maturity, which is what lets step 4 work.

Also, you might want the loan to end the day the PT does.

With IRIS, you can set the term to the PT’s expiry.

IRIS quotes any number of days, so you repay on the same day the PT pays out.

gave this a try and wow, it’s so cool.

this is what i did:

- used wstETH as collateral
- borrowed USDC (rate: 4.85%)
- set maturity at 90days
- used the borrowed usdc to get @pendle_fi pt
- @3janexyz sUSD3 pt 26.3%
wait for pt to expire, claim and repeat before your debt maturity hits 🤝

IRIS on mainnet, walked through by @0xCheeezzyyyy.

Fixed for the full term. Settled on Aave, Morpho and Spark.

The long-awaited @iris_credit mainnet is finally live🫡

For those unfamiliar, IRIS is building a fixed-rate borrowing layer for DeFi, allowing users to access more predictable borrowing costs by coordinating liquidity across existing lending markets.

This is a critical step towards bringing greater certainty to DeFi borrowing imo esp. for users who want to manage their financing costs without constantly worrying about fluctuating rates.

The launch begins with a limited Core Phase, supporting:

🔹 Collateral: cbBTC, wstETH & WBTC

🔹 Borrow USDC: via Aave/Morpho

🔹 Borrow USDT: via Aave/Spark/Morpho

The initial rollout comes w/ predefined limits and a narrower set of supported assets, which the team plans to expand progressively.

What interests me most is the broader opportunity for fixed-rate financing in DeFi.

While variable-rate lending has become a cornerstone of onchain finance, predictable borrowing costs are equally important for longer-term financial planning, leveraged strategies + capital efficiency.

IRIS is tackling this by building on top of existing lending infrastructure rather than trying to replace it.

Ofc, the real test will be how reliably its fixed-rate mechanism performs as liquidity, utilisation + market rates change.

But it's exciting to finally see the protocol move from concept to live deployment.

Keen to see how IRIS develops from here 🤝

A very clear breakdown of how IRIS works, by @bonnazhu.

IRIS takes the lender out of the design. Fixed-rate risk goes to solvers who choose to hold it and bond every quote they make.

Liquidity and loan stays on Aave, Morpho and Spark.

个人觉得这要比从零搭建一个利率互换市场更务实
至少对 Borrower 来说,没比这更友好的模式:

- 自己定义包括借款天数在内的条款
- 发起 RFQ 询价,Solver 报价竞争
- 直接在 Aave / Morpho / Spark 上成交,利率锁定

等于是把原本机构间 OTC 借贷模式搬到了链上,做成了谁都能用的标准化流程。哪天你看到一个比较诱人的 Farming 或者限时的 Deposit Vault 机会,有利差能套,通过这个借一笔,就是最方便的了。

区别在于 Lender 端的流动性仍旧来自于 Aave / Morpho / Spark 这些市场,而非 Solver,后者不过是和 Borrower 做了一笔利率互换(做空浮动,做多固定),只押一笔 Bond 作为保证金,不占用本金。

因此,Solver 的杠杆其实很高。

如 10 万 USDC 借 30 天,大约只要 250 USDC 的保证金,就可以 Underwrite 整笔 USDC 贷款“固定减浮动”的利差敞口。贷款存续期内,浮动利率持续低于固定利率,Solver 就是赚的;如果高于,就扣 Bond 保证金,扣到清算线,Solver 被清算,这笔贷款退回成普通的浮动借款。

本质上 Solver 就是一个利率交易台,做空借贷利率。

只要有其他地方可以把这个敞口对冲掉,那整个流程就能跑起来。例如那些业务本身隐含做多利率,利率越高、收入越高的角色如 Curator,似乎就是合适的 Solver 人选。

---------------------------------------

之所以想写一写 IRIS,觉得挺有意思,

是因为这套结构里,对手方设计和过去的做法不一样。

过去链上固定利率借贷困在 Lender 和 Borrower 的直接匹配上。链上借贷利率本身相对于 Crypto 原生收益来说并不高。要让 Lender 放弃这些机会,去接受一个高一点点的固定利率,放弃流动性、锁定期限,机会成本太大。

这也是为什么 Notional 等老一代固定利率借贷协议,关门的关门、转型的转型。而 Pendle 绕开了借贷利率,拆的是新币、积分这类收益更高、波动更大的资产,让要确定性的 PT 买家和要投机的 YT 买家互为对手方去博弈,本质上是投机者在补贴固定收益,反倒先找到了 PMF。

有一定理由相信,IRIS 是借鉴了过去的经验和教训,

把 Lender 从产品设计里剥离掉,由利率交易台替代。

顺着这个思路去看市面上目前固定利率借贷的两种做法,

一种是重复过去的路,继续单独开辟一个固定利率市场,例如 EVM 上的 Morpho Midnight、Solana 上的 Loopscale。它们做得比老一代更好,财力显然也更雄厚,有钱去让人铺流动性,但本质上还是在撮合 Lender 和 Borrower。且为了让订单簿有深度,期限只能集中在少数几个到期日,Borrower 反过来被到期日绑住。

另一种是在现有浮动利率市场之上,搭一个利率互换市场。它同样不需要 Lender 做任何改变,但 Borrower 得自己去上面对冲,多了额外的操作。而且既然是做市场这种标准化产品,所以依旧会受限于几个固定的到期日。

IRIS 的做法算是比较务实了。

Back in August, @castle_labs spent weeks mapping fixed-rate lending onchain.

If you want to understand why fixed rates onchain are hard, and the different ways teams are trying to solve it, reminder that their report is the best place to start.
