Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.syno.finance/developer-docs/tokens.md). # Tokens ## Tokens There are 4 major tokens in the protocol (visit the [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details) * SYNO - the protocol token * tSYNO - locked SYNO for users who want to convert their NEWO tokens to SYNO tokens * rCT - rewards claim token - veNEWO holders who converted their NEWO tokens to SYNO tokens, can receive also rCT tokens * vlSYNO - locked Balancer ETH-SYNO LP tokens ### SYNO A standard ERC20 token ### vlSYNO A non-transferable ERC20 token. Earns a portion of the protocol fees (visit [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details) `vlSYNO.stake(...)` * Allows users to lock their Balancer ETH-SYNO LP tokens for a certain period of time * Params * `amount` * `lockPeriod` - `ONE_MONTH` | `THREE_MONTHS` | `SIX_MONTHS` | `TWELVE_MONTHS` * the longer the lockPeriod, the more bonus fees it earns, visit the [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details `vlSYNO.requestUnstake(...)` * Initiates the unstaking process, which involves a 7 days cooldown period. After you request an unstake, you have to wait at least 7 days to be able to unstake your vlSYNO and receive your LP tokens * Params * `index` - the index of the sake to be unstaked. Can be retrieved from the `vlSYNO.Staked` events `vlSYNO.unstake(...)` * Finalizes the unstaking process initiated by `vlSYNO.requestUnstake(...)`. Retrieves the LP tokens and returns them to the user. * Params * `index` - the index of the sake to be unstaked. Can be retrieved from the `vlSYNO.Staked` events `vlSYNO.restake(...)` * When a vlSYNO stake expires, it no longer earns bonus APY, instead of unstaking it, waiting 7 days cooldown period and then staking it again, a user can immediately restake it. * Params * `index` - the index of the sake to be restaked. Can be retrieved from the `vlSYNO.Staked` events ### TokenConverter This smart contract allows users to convert their NEWO tokens to tSYNO and rCT tokens. `TokenConverter.ClaimInput` The input for `TokenConverter.convertWithProof(...)` function. The input values must match the merkle tree leafs: * `amount` * must be lesser or equal to `rCTCap/multiplier` * this much NEWO will be converted to tSYNO * `proof` - merkle tree proof * `index` - merkle tree index * `rCTCap` * `multiplier` `TokenConverter.convertWithProof(...)` * This function converts NEWO to tSTYNO and rCT tokens * This function should called once only. If you want to convert your NEWO in stages, use `TokenConverter.convert(...)` for subsequent conversions * Should be only called if the user is eligible to rCT token (veNEWO stakers, visit the [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details) * It's required to use this function if the user is eligible to rCT tokens * Params * `ethereumClaim` - a proof of rCT eligibility from Ethereum * `avalancheClaim` - a proof of rCT eligibility from Avalanche * `disclaimerSignature` - a signed disclaimer (`TokenConverter.disclaimer`) `TokenConverter.convert(...)` * **If your are eligible to rCT token (veNEWO stakers, visit the** [**tokenomics**](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) **for more details), call `TokenConverter.convertWithProof(...)` first.** * This function converts NEWO to tSTYNO and rCT tokens * For users who are veNEWO stakes and called `TokenConverter.convertWithProof(...)` first * For all the other users * Params * `network` * The origin network for the NEWO you want to convert * `ITokenConverter.Network`: `ETHEREUM` | `AVALANCHE` * `amount` * this much NEWO will be converted to tSYNO * if you are eligible to rCT tokens and called `TokenConverter.convertWithProof(...)` previously, you'll receive rCT tokens as well. * `disclaimerSignature` - a signed disclaimer (`TokenConverter.disclaimer`) ### tSYNO A non-transferable ERC20 token. Earns a portion of the protocol fees (visit [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details). Can be obtained through NEWO token conversion through `tSYNO.unstake(...)`. `tSYNO.unstake(...)` * tSYNO tokens will be converted to SYNO tokens when unstaked. If unstaked before the lock period elapses, a penalty is applied. The penalty starts at 90% and decreases linearly to 0% over the lock period. The penalty is transferred to the protocol treasury. * Unstaking tSYNO tokens will result in permanently burning corresponding rCT tokens. * If you have a suprplus of tSYNO tokens over your vlSYNO allowance, unstaking them will not result in burning rCT tokens (visit the [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details) * Params * `amount` ### rCT A non-transferable ERC20 token. Earns a portion of treasury yield (visit [tokenomics](https://docs.syno.finance/documentation/tokenomics-and-rewards/syno-tokenomics) for more details). Only staked rCTs earn the yield. You can stake/unstake any time with `rCT.stake()` and `rCT.unstake()`. ### RewardsDistributor For every asset distributed by the protocol to the users (rewards, emissions, yield) there is a `RewardsDistributor` instance. `RewardsDistributor.claim(...)` * Allows to claim rewards for multiple epochs * Params * `inputs` - a list of merkle tree proofs (`RewardsDistributor.ClaimInput`) for the distribution claims
