Diving into basic structure upgrades coming with Bancor 3–from the introduction of a brand new sort of pool token, to the unleashing of composable liquidity.
Constructed on Ethereum, Bancor is a decentralized trade (DEX) that ushered the liquidity pool, pool token, and automatic market maker (AMM) ideas into DeFi again in 2017.
Single-sided pool token
Bancor is introducing an array of upgrades that will likely be rolling out in three levels–dubbed ‘Daybreak,’ ‘Dawn,’ and ‘Daylight.’
Let’s begin with the introduction of a novel, single-sided pool token, which is on the heart of the Bancor 3 remake.
With the brand new structure, the power to stake single-sided, and the safety from impermanent loss (IL) are about to change into an inherent characteristic of the system, versus being managed by a second layer of contracts.
The unique design for traditional pool tokens makes use of two values to compute the worth of particular person tokens within the pool: the whole provide of pool tokens and the stability of the tokens inside a liquidity pool Bancor 3 single-sided pool tokens are designed to be agnostic to the true token balances of the community and as an alternative discuss with a protocol-wide Staking Ledger that has no data of IL.
As such, the valuation of Bancor 3 pool tokens is unaffected by IL, whereas charges earned from market-making actions are appended to the Staking Ledger – permitting the pool tokens to understand.
With this in thoughts, opposite to Bancor v2.1 the place full IL safety is collected by staking tokens in a pool for 100 days or extra, Bancor 3 introduces full IL safety from the onset (“Instantaneous IL safety”).
“Superfluid” DeFi Liquidity
By eliminating the IL, Bancor discovered a treatment for protocols not accepting “pool tokens” as staking collateral.
On account of IL safety and the accrual of buying and selling charges–single-sided pool tokens solely rise relative to the HODL worth of the underlying asset–which makes them an excellent type of native staking collateral.
In keeping with Nate Hindman, the Head of Progress at Bancor Protocol, Bancor’s proposed answer comes as extra DeFi protocols are launching native staking performance, leaving their token holders with a troublesome alternative: present liquidity within the native token on a DEX, or natively stake the token within the protocol.
With Bancor 3, customers might not want to decide on, and that is the place the brand new single-sided pool token design absolutely shines.
“The concept is straightforward: on-chain liquidity can be utilized concurrently for a number of functions. Till now, the primitives haven’t existed to help it, however which may be altering with the upcoming launch of Bancor 3’s single-sided pool tokens–and it may pave the best way for a model new strategy to composable liquidity–one wherein LPs don’t have to resolve between incomes yield in AMMs and natively staking their tokens. They’ll do each,” defined Hindman.
In keeping with him, all of it begins with third-party protocols accepting Bancor’s single-sided pool tokens as native staking collateral. For instance, Synthetix may settle for bnSNX (a single-sided pool token generated when a person deposits SNX in a Bancor 3 pool) as staking collateral within the Synthetix Protocol.
“Synthetix may, theoretically, help bnSNX as native staking collateral in Synthetix. In consequence, customers would be capable of deposit SNX within the SNX pool on Bancor, generate bnSNX pool tokens after which stake the bnSNX in Synthetix,” Hindman clarified.
This basically permits DeFi customers to concurrently unlock yield at each side–accruing buying and selling charges from Bancor, whereas tapping into native staking rewards from the third-party protocol.
“Omnipool” and “Infinity Swimming pools”
In addition to the Staking Ledger, the brand new structure additionally introduces a vault-style group of the protocol.
Going ahead, Bancor Community will retailer all tokens from throughout the community, together with its BNT in a single contract, as an alternative of storing its tokens in liquidity swimming pools. Nonetheless, the phantasm of particular person liquidity swimming pools will stay–containing nothing greater than the pool logic.
Bancor is looking these options the “Omnipool” and “Infinity Swimming pools” within the Daybreak part.
In distinction to the earlier model, which required trades to be processed through BNT, creating an additional transaction and added fuel prices, the brand new model’s Omnipool will enable all trades on the community to occur in a single transaction–lowering fuel prices, which makes liquidity staked on the protocol extra capital environment friendly.
Within the present model of Bancor, customers have to attend till house opens up in a pool earlier than they’re allowed to deposit their tokens, however with the introduction of Infinity Swimming pools these limits are gone, and anybody can contribute as a lot as they like.
Within the present model, solely Bancor may stimulate its liquidity swimming pools with BNT rewards. In Bancor 3, depositors stand to revenue from dual-sided rewards in Bancor 3, as third-party protocols may supply rewards in their very own native token on their swimming pools.
Moreover, customers received’t should manually re-add their rewards to the pool, which prices them fuel every time, since in Bancor 3 each buying and selling charges and liquidity mining rewards are auto-compounding.
Because of this earnings are immediately re-added to the pool–enhancing the community’s liquidity and rising customers’ potential to passively earn extra charges and rewards.
Lastly, with the proposed improve, BancorDAO positive factors the facility to not solely present protocol-owned BNT to its swimming pools and generate charges for the protocol, but additionally to vote on shrinking the protocol-owned BNT in any pool that’s under-performing, and redirect the protocol’s liquidity to extra worthwhile swimming pools.
Amongst different cutting-edge options which might be being ushered in by Bancor’s largest proposed replace up to now additionally embrace multichain and Layer 2 help, in addition to the mixing of Chainlink Keepers, to allow extra environment friendly token burning and withdrawals.
The unconventional redesign will come accompanied by a revamped front-end, permitting a single-click migration from Bancor V2.1 to Bancor 3.
That includes a abstract of crucial day by day tales on the earth of crypto, DeFi, NFTs and extra.
