Jito Launches BAM Maker Plugin, Further Boosting Prop AMM Execution

Jito Labs, the team building Solana’s market layer, has shipped its first eagerly-awaited BAM plugin, promising to elevate market maker efficiency and trader execution.

The BAM maker plugin gives prop AMMs a dedicated transaction pathway for updating quotes on 50ms scheduling increments, delivering a level of predictable, TradFi-standard execution precision that has never existed on a decentralized network.

Beyond improving onchain market structure, Jito's debut BAM plugin is expected to boost revenue for 347 validators currently running the BAM client, representing 28% of Solana's total network stake.

BAM Plugin to Bring Predictable Execution to Solana DeFi

Despite immense progress at Solana’s market layer, which already consistently outperforms centralized exchanges, builders argue that the onchain scheduling layer is still far from its final form.

Every validator can run a different scheduler, meaning transaction ordering changes with every new leader. At a 400ms slot time, that is a new variable every 1.6 seconds that market makers, or prop AMMs in this case, cannot control or predict, making it difficult to quote prices efficiently.

As it stands, Solana’s scheduler fragmentation and unpredictability means that market makers are forced to make avoidable tradeoffs, like widened quotes and surplus oracle updates. 

Where widened quotes force larger spreads and poorer trade execution, high-frequency oracle updates are an inefficient use of compute, often resulting in reverted transactions and wasted blockspace.

“The economics of market making depend on knowing your order will land when you expect it to. This is v0. We are actively working with all of the major market makers on Solana, as well as other institutional participants, to understand how we can improve the maker plugin and what other plugins we should ship next.” - Lucas Bruder, CEO of Jito Labs

Jito’s maker plugin aims to solve these constraints, providing prop AMMs with a dedicated transaction pathway, enabling them to predictably update quotes in 50ms batches. 

At the end of each batch, the latest transaction from the dedicated maker port is placed at the top of the next batch. This happens regardless of priority fee, effectively giving makers priority over takers, and protects stale quotes from getting sniped by takers. 

In Solana’s current market structure, makers are lumped into the same 400ms slot time as all other participants. By cutting down transaction batching to 50ms, Jito argues that makers running the plugin will be able to deterministically price quotes 8x more frequently. 

What Does This Mean For Traders?

With market makers enjoying more predictable ordering and more frequent pricing updates, DeFi users can ultimately expect tighter spreads and better trade execution. 

Beyond tighter and more frequent price quotes, prop AMMs will also be able to reallocate compute spend far more efficiently. Instead of wasting resources trying to land transactions in an unpredictable scheduling layer, makers will be able to direct compute more efficiently towards accurate pricing updates.

Liquidity depth should also improve. By running the maker plugin, prop AMMs no longer run the risk of having their stale quotes sniped by predatory takers. In practice, this enables them to more efficiently price risk and provide deeper liquidity at each price level. For the end user, this translates to reduced slippage and better value in every trade.

“Institutional market participants evaluate trading venues on whether execution is predictable and whether the infrastructure can support how they actually operate. Those have been open questions for Solana. The maker plugin is a meaningful answer to both.” - Rebecca Rettig, COO and CLO of Jito Labs

Prop AMMs on Solana have already demonstrated they can match or beat centralised exchange execution quality under current conditions. According to Jump Crypto’s research, prop AMMs beat centralized exchanges in 99.3% of trades at entry-level fee tiers.

The BAM Maker plugin removes one of the remaining structural inefficiencies propping up the spread premium that market makers on Solana are still forced to endure.

Plugins to Boost Validator Revenue on 28% of Solana Stake

Traders and market makers are not the only ones to benefit from the rollout of Jito’s first BAM plugin. For the 347 validators running the BAM client, the maker plugin serves as an additional revenue stream, distributing priority fees paid by prop AMMs among contributing operators.

At launch, makers leveraging the first BAM plugin will pay 20 lamports (0.00000002 $SOL) per CU in priority fees. While this may seem inconsequential at first glance, it’s worth noting that prop AMMs typically spend anywhere from 50-200 CUs per oracle update. When running the Maker plugin, leading prop AMMs will be capable of updating prices once every 50ms, ultimately firing off 20 updates per second.

Jito has confirmed that it will continually monitor Maker plugin activity and revenue capture, and may adjust fees.

The maker plugin launch comes off the back of growing demand for the BAM client. According to Blockworks data, BAM has enjoyed consistent YTD adoption in 2026, now running on 27.71% of network stake.

With BAM’s first plugin now out of the lab and onto mainnet, Jito is inviting the network’s builders to come forward with fresh suggestions on how plugins could solve execution challenges across all areas of the onchain economy.
