This section describes different op codes of AMM smart contracts v2
Last updated
The section contains separate documents for each smart contract used in AMM:
Definitions of terminology used can be found in
Example schemes can be found here:
A table with DEX v2 op codes:
custom payload & nested operations after swaps
chain multiple swaps on the same Router
chain multiple swaps on different v2 Routers
custom refund address and payload on swap failure
deadline for tx completion
custom payload after liquidly provision
improved initial liquidity locking management, no coins are lost anymore
now always mints a maximum possible amount of lp tokens to user even if provision ratio is different from current one in Pool
single side liquidity provision
deadline for tx completion
referral fees are stored in Vault contract
custom referral fee value in each swap (maximum 1%)
now uses a custom op code for ton transfers
ton transfer to user is non-bouncable
improved gas management
can chain ton transfers between 2 pTON wallets (to chain pTON swaps on v2 Routers)
LpAccount and Vault are deleted if they have 0 tokens on balance to avoid paying storage cost
better error management: no coins are lost if Pool doesn't exist / payload is not correct
complete refactoring of the codebase and usage of libs in masterchain to make all operations cheaper
fixed various excesses issues
fixed some Pools having broken get_jetton_data
off-chain get_expected_outputs
off-chain get_expected_tokens
off-chain get_expected_liquidity
on-chain getter_expected_outputs
on-chain getter_expected_tokens
on-chain getter_expected_liquidity
user-called collect_fees
