✅ DBC Program Update containing Swap2 is LIVE

You can now process swaps via 3 different swap modes: Exact In, Partial Fill or Exact Out

❗️NOTE: ALL Trading Terminals are to change to swap2`endpoint - `swapMode: 1 (PartialFill)
The previous swap function was a swap ExactIn function that processes swaps based on the exact amount in, not taking into account how much baseMint tokens are left available in the curve to be sold. With swap2, we introduced 2 additional modes, PartialFill and ExactOut that trading terminals can use to accurately process trader swaps without causing traders to overpay for the last swap in the curve due to lack of baseMint tokens.

P.S.: We will not be processing any refund requests from traders who overpaid from DBC last swap, in 1 weeks’ time.

For the DBC Program:

Added:
- Added new endpoint swap2, that includes 3 different swap_mode: 0 (ExactIn), 1 (PartialFill) and 2 (ExactOut)
- Emit new event in 2 swap endpoints EvtSwap2, that includes more information about quote_reserve_amount, migration_threshold and included_fee_input_amount


❗️the previous swap function is still available and all changes are backwards compatible

For the DBC Typescript SDK:

Added:
- Added new endpoint swap2, that includes 3 different swap_mode: 0 (ExactIn), 1 (PartialFill) and 2 (ExactOut)
- Added new endpoint swapQuote2 that includes 3 different swap_mode: 0 (ExactIn), 1 (PartialFill) and 2 (ExactOut) and returns SwapResult2
- Added prepareSwapAmountParam helper that calculates your token amountIn in lamports
- Added getCurrentPoint helper that helps you to getSlot() or getBlockTime() depending on your activationType

Changed:
- swapQuote now returns SwapResult instead of QuoteResult
- Deprecated swapQuoteExactIn
- Deprecated swapQuoteExactOut

Adding on to the DBC Program Update - Swap2 feature:

ALL trading terminals to take note:

- ensure that you index swap2 and EvtSwap2
- ONLY change the swap ix from swap to swap2 with swapMode: 1 (partialFill) on 22nd August, Friday (9am UTC) (you can test this on mainnet already)

+ For Trading Terminals to take NOTE: it is crucial for all trading terminals to only change their swap ix from `swap` to `swap2` to ensure that the charts across all trading terminals are synchronous

dbc idl: https://github.com/MeteoraAg/dynamic-bonding-curve-sdk/blob/main/packages/dynamic-bonding-curve/src/idl/dynamic-bonding-curve/idl.json

P.S. we will be extending the refunds for last swap till Friday 29th August, 9am UTC

Reminder for ALL Trading Terminals integrating our Dynamic Bonding Curve Program to switch to use swap2 and also to index swap2 and EvtSwap2

Because of our high fees in our Anti-Sniper Suite, all trading terminals are encouraged to use the decoded EvtSwap2 instead of transfer IXs to plot their charts.

This is crucial to get the accurate token prices before/after fees depending on trade direction and fee collection modes

The logic to display accurate price charts is as follow:

if excludedFeeInputAmount != includedFeeInputAmount then 
-> excludedFeeInputAmount <> outputAmount

if excludedFeeInputAmount == includedFeeInputAmount then
-> excludedFeeInputAmount <> outputAmount + tradingFee + protocolFee + referralFee

gmet everyone

as you all know, our DBC program is as customizable as a Subway sandwich.

due to it being fully customizable, we noticed a few bad actors using this customizability to wash trade and create inauthentic trading volume.

we WILL be introducing stricter guardrails on our program by bumping the minimum trading fee to at least 0.25%.

we want to protect our LPers and trench warriors, while still being the most customizable and dynamic liquidity layer for all launchpads to build on top of.

if you are a launchpad building on top of DBC and this update affects you, let me know either via discord ticket or telegram (if u have my tg)

⏰ DAMM v2 Program Update containing Swap2, EvtSwap2, and Rate Limiter is COMING SOON

❗️NOTE: This update contains BREAKING CHANGES

📖 View the full announcement is here on discord

📆 ETA: Thursday, 9th October 2025, 11am UTC+8 (in ~1 week)**
Ideally, you should deploy your update a short period before our program deployment (e.g. by 9th October, ~1030am UTC+8)

We’ll notify if the timeline shifts and when the program is deployed.

⏰ DBC Program Update containing Increased Minimum Base Fee and Error Surplus is COMING SOON

📆 ETA: Tuesday, 4th November 2025, 11am UTC+8 (in ~1 week)**

❗️NOTE: This upcoming update contains BREAKING CHANGES for Trading Terminals who are using swap or swap2 (exactIn or exactOut). Instead of taking a surplus for swap modes exactIn or exactOut, the program will return an error if pool.sqrtPrice is more than poolConfig.migrationSqrtPrice.

require!(
      next_sqrt_price <= config.migration_sqrt_price,
      PoolError::SwapAmountIsOverAThreshold
);

Important Changelogs:

Breaking Changes:
- Swap ExactIn and SwapExactOut won't take surplus for the last swap, instead of returning error if pool.sqrt_price is over migration_sqrt_price
- Changing min base fee from 1 bps (0.01%) to 25 bps (0.25%). Effected to endpoints: create_config, initialize_virtual_pool_with_spl_token and initialize_virtual_pool_with_token2022. Not able to work if min base fee less than 25 bps.

Changed:
- A pool creation fee of 0.01 SOL will be charged if the pool collect_fee_mode is CollectFeeMode::OutputToken and base_mint is token_2022 (endpoint: `initialize_virtual_pool_with_token2022`)
- Migration Fee cap has been increased from 50% to 99%

Deprecated:
- Endpoint migration_damm_v2_create_metadata and migration_metadata account as migrator doesn't need migration_metadata anymore when migrating to a DAMM v2 pool
