Bancor releases no-liquidation lending with Vortex as AMMs continue diversification

Automated market maker change Bancor has rolled out a new mechanism that permits customers to extend their capital effectivity whereas offering liquidity in its swimming pools.

Called Vortex, the answer permits customers offering liquidity in BNT, Bancor’s utility token, to borrow funds whereas persevering with to acquire yield from swap charges.

The Vortex mechanism reworks the prevailing mechanism of vBNT, a particular model of the BNT token that entitles customers to take part in governance. The voting token is mechanically obtained when staking BNT right into a liquidity pool, and it may be outlined as Bancor’s pool token.

The Vortex proposal provides performance to vBNT, creating an infrastructure that permits customers to promote the token for the unique BNT. Once vBNT is transformed, customers can change it into another asset.

The vBNT sale mechanism makes Vortex a no-liquidation lending platform, letting liquidity suppliers obtain their future rewards instantly, in a similar manner to Alchemix. Since their principal continues to accrue swap charges, the mortgage will ultimately repay itself.

The “no-liquidation” a part of the mortgage comes from the truth that vBNT and BNT are basically the identical token, and the rise in value of the BNT collateral may be very more likely to be mirrored by vBNT. BNT staking creates vBNT at a one-to-one ratio, however the value relationship between the 2 shouldn’t be simple.

Combining protocol income and lending ends in complicated tokenomics

The vBNT token’s value is derived from a BNT/vBNT AMM pool, thus largely being outlined by the market. A possible arbitrage mechanism implies that vBNT is unlikely to ever be price greater than 1 BNT, as arbitrageurs may merely stake BNT, promote the vBNT, and acquire extra BNT than they began with. The cycle may very well be repeated an infinite variety of instances till the vBNT value returns beneath 1 BNT.

At the identical time, vBNT has no value flooring as a result of the arbitrage mechanism can’t work in reverse. As Mark Richardson, the creator of Vortex, defined to Cointelegraph, Bancor makes use of inner data to outline possession inside an AMM pool. This is a big distinction from fashions like Uniswap’s pool tokens, that are the only real marker of liquidity possession. The vBNT may very well be used to redeem a BNT liquidity pool provided that that tackle had already created one.

To assure that vBNT maintains some worth within the absence of a redemption mechanism, the protocol will probably be conducting a buyback-and-burn technique on the token. A governance-defined portion of the protocol’s charge income will probably be diverted to periodically purchase and destroy vBNT from the pool with BNT, offering a continuing shopping for strain.

This has the added results of making a sink of BNT and vBNT. Since one vBNT unlocks one BNT, destroying vBNT provide creates an imbalance with the tokens contained in AMM swimming pools. A portion of these tokens would thus stay locked within the swimming pools without end, although this could not influence liquidity withdrawal for particular person liquidity suppliers because of the giant extra capability — an analogous mechanic happens with chilly wallets on centralized exchanges.

The vBNT token mechanics have quite a few fascinating ramifications. In addition to the flexibility to borrow whereas persevering with to obtain yield, liquidity suppliers are additionally capable of leverage their liquidity to obtain extra swap charges. The value of vBNT straight impacts how leveraged the system might be, as costs near 1 BNT may assist an virtually infinite leverage issue. At the identical time, as extra LPs enter leveraged positions, the worth of vBNT is more likely to lower and restrict the leverage multiplier. An infinite leverage scenario would extract worth from the protocol, however Richardson is assured that the market-based pricing mechanism shortly makes this expensive and finally impractical.

Liquidity is not a problem, however quantity is trailing behind

The Bancor protocol has deployed each useful resource it has to attract liquidity into the protocol. Between the improvements of single-sided liquidity provision and impermanent loss insurance, launched with V2.1, it has additionally launched aggressive liquidity mining applications. The Vortex proposal is one more instrument that would draw liquidity in by introducing leverage on AMM swimming pools.

Bancor’s liquidity marketing campaign has been a demonstrable success. With $1.8 billion in whole worth locked, it broke into the “billion-dollar TVL club” to turn out to be the eighth within the decentralized change rankings on DeFi Llama. While it’s behind most of its direct rivals such as Uniswap or SushiSwap, Bancor has grown a lot sooner as it began the yr at simply $140 million in TVL.

The development in liquidity hasn’t mechanically resulted in additional quantity, nonetheless. Though Bancor is within the top-five by quantity on Ethereum at $430 million per week, Uniswap dominates the market and attracts virtually 17 instances as a lot quantity regardless of solely having barely greater than twice the TVL. In Richardson’s view, the Bancor crew could have had misguided expectations in its pursuit of liquidity:

“There was this assumption, I would say — and we might not have even been aware that it was an assumption — that if the TVL gets high enough, it will just attract traders […] And if everyone’s using aggregators, then that’s really good for us because we just have to offer the best product at the lowest rates and traders will just use us.”

The actuality turned out to be much less idealistic than anticipated as the crew came upon. “It turns out no one uses aggregators, and traders hardly ever are using the pools with the best rates,” Richardson added. “They just do whatever they’re going to do.” Nate Hindman, head of development at Bancor, had his personal view of why Uniswap is so dominant:

“I think a big part of that has been this sort of ‘Uniswap gems’ movement that was a DeFi summer thing, where there’s all these new tokens that are launching pools on Uniswap. So, Uniswap is the only place to get these ‘gems.’”

Hindman’s evaluation appears to be in line with Uniswap’s quantity knowledge. According to its statistics, the quantity distribution is closely skewed towards smaller tokens. Pairs between Ether (ETH), Bitcoin (BTC) and stablecoins take about 25% of the overall quantity, whereas the remainder of the record is populated largely by low-capitalization tokens which might be onerous to entry on different platforms.

As Hindman revealed, capturing the “long tail of tokens” will probably be Bancor’s subsequent main goal. One potential proposal for that’s the Origin Pool, which permits creating “synthetic” swimming pools paired with ETH, whic is seamlessly changed with BNT by the protocol. This would clear up long-standing onboarding friction for Bancor, as tasks wishing to get listed wanted to carry BNT along with their very own token.

After the Uniswap V3 announcement and its heavy focus on swap efficiency — partially on the expense of liquidity pool automation — it turned clear that AMM tasks are beginning to diversify into totally different niches. With SushiSwap’s focus on additional features such as margin buying and selling, Balancer’s push for composability, and Bancor’s strategy specializing in the LP and the BNT token, the AMM area is turning into increasingly different.
