The lender no longer most effective earns hobby in keeping with annual proportion yield, reminiscent of standard lending, but in addition further rewards within the type of SLND tokens, that are the local tokens of Solend.
Solend has a prime international liquidity pool, with a number of smaller remoted and permission swimming pools. Tokens having dependable oracles and thick liquidity may also be indexed in the primary pool. Maximum tokens, then again, are indexed on remoted swimming pools first prior to being shifted to the primary pool.
Remoted swimming pools are smaller ones for checklist tokens with much less liquidity and extra volatility. Permission swimming pools permit any person to create an remoted pool at the protocol.
The writer of an remoted pool earns 20% of the origination charges generated within the particular pool. Tokens to be had at the token record, together with a predetermined business quantity, will seem at the checklist.

Dangers related to the use of Solend

Incorrect feed by way of oracles
Oracles reporting the fallacious feed may play havoc on Solend. The associated fee feeds of Pyth Community and Switchboard cause liquidations at the platform. Those oracles reporting unsuitable costs would lead to wrongful liquidations.
On Nov. 2, 2022, Solend did undergo an oracle exploit, culminating in $1.26 million of dangerous debt. The comparable swimming pools have been disabled and exchanges have been knowledgeable concerning the exploiter’s cope with.

100% usage of budget
Like several DeFi swimming pools, a chance situation is 100% usage of budget. One can not take a mortgage if no property stay within the pool. The issue is termed 100% usage. On the other hand, if debtors stay repaying their loans or new provides stay arriving, this kind of drawback would possibly not rise up.
But some other chance risk is related to liquidations. Even though Solend provides overcollateralized loans, one can not put out of your mind that the crypto marketplace is unstable, with fluctuating asset values that might end result within the liquidation of budget of an unsuspecting consumer. This makes it necessary for everybody to pay shut consideration to their loans and investments.
Massive, unmarried debtors
Being a big lending pool, a key vulnerability of Solana is the presence of a big, unmarried borrower, referred to as a whale. Whales have an oversized presence within the protocol. This led to a June 2022 crash involving a whale borrower.
A Solana whale with $108 million nearly crashed the Solana community in June 2022. The protocol slightly have shyed away from the liquidation of 95% of SOL deposits in its lending pool. Let’s dig a little bit deeper into the way it all came about.
The whale had an impressive mortgage of $108 million value of USD Coin (USDC) and Tether (USDT), sponsored by way of collateral of $170 million value of SOL. The entirety used to be high-quality whilst the cost of SOL used to be top, but if it tanked round June 15, the whale’s account used to be at the verge of the liquidation threshold. It would have led to over $21 million of SOL getting dumped in one shot, with critical repercussions out there.
The venture builders attempted to touch the whale to no avail. They have been compelled to publish on Twitter and Reddit, urging the whale to touch them, which spooked many different customers who started to tug out their budget. The builders ultimately controlled to touch the whale, who added extra collateral.
On the other hand, prior to the whale added the collateral, the builders — of their quest to regulate the wear and tear — proposed emergency powers to regulate the account within the tournament of liquidation. This earned them dangerous press, because it used to be towards the spirit of decentralization. The general measure used to be to arrange a borrower ceiling of $50 million.
The way forward for Solend
Solend has introduced the facility of DeFi to the Solana community, providing customers many alternatives that experience the prospective to improve their earnings. Even though the whale factor laid naked the vulnerability of the protocol, the silver lining used to be the builders’ skill to maintain issues. Crypto remains to be a brand new business the place persons are finding out at the transfer. The a success dealing with of the whale factor to the pride of maximum stakeholders raised the protocol’s credibility.
Moreover, Solend brings a powerful DeFi part to the Solana ecosystem. Vulnerabilities however, the appliance is intriguing to tinker with, and because the loopholes get plugged, extra customers would possibly in finding it thrilling.
