MagicBlock Releases Validator v1.0 for Ephemeral Rollups on Solana, With New Session and Commit Fees

MagicBlock released Validator v1.0 on 6 October 2026, the first 1.0 version of the software that runs its Ephemeral Rollups on Solana. The release was tagged on GitHub that day, and MagicBlock's blog post says it follows "more than a year and a half of building, testing, and refining". Alongside new developer features, the post sets out a fee schedule for using the rollups and a rebate scheme for the busiest applications.

Validator v1.0 is a version milestone for software already in use. MagicBlock's Ephemeral Rollup documentation lists four rollup validators on Solana mainnet (Asia, Europe, the United States and one running in a trusted execution environment), and the project's release history shows version 0.16.1 shipping a day earlier, on 5 October. Flash Trade said in June 2026 that its V2 perpetuals exchange used MagicBlock's engine to offer latency as low as 50 milliseconds, as we covered when Flash Trade V2 left beta; Flash Trade has since wound down its exchange.

How Ephemeral Rollups borrow accounts from Solana

An ephemeral rollup is a temporary, fast execution environment that takes over specific Solana accounts for a while and then hands them back. According to MagicBlock's documentation, an application delegates accounts to MagicBlock's Delegation Program, which locks them on Solana. Transactions touching those accounts then run on a rollup validator, the operator commits the resulting state back to Solana periodically or on demand, and undelegating returns the accounts to their original owner.

The arrangement is closer to running a bar tab than paying for each drink: activity piles up off to the side and Solana records the settled result. MagicBlock's documentation claims 10-millisecond block times inside a rollup and charges nothing for ordinary rollup transactions in the current release. Those performance figures are MagicBlock's own, and the release names no applications or usage numbers.

What Validator v1.0 adds: Intent Bundles, Magic Actions and Magic ATAs

Most of the release is about letting an application hand the validator a multi-step job instead of stitching the steps together itself. MagicBlock's blog post describes five additions:

• Intent Bundles let a developer request several steps from a single rollup transaction, with the validator handling the sequence.
• Magic Actions let Solana programs use the updated state during settlement. Per the blog, an action included in the same Solana transaction as a commit executes atomically with it, so a failed action reverts the transaction.
• Post-Delegation Actions start work automatically when an account reaches the rollup, and support encrypted instructions for workflows that need privacy.
• Magic ATAs let a user send tokens to a recipient on the rollup without first creating the recipient's associated token account (the per-wallet account that holds a given token) on Solana or paying its upfront cost.
• Ephemeral Accounts hold temporary data on the rollup, which MagicBlock says costs a fraction of funding an equivalent account on Solana.

MagicBlock says the combination lets a payment start on Solana mainnet, execute privately in a rollup and settle back on mainnet. The privacy rests on hardware: MagicBlock's Private Ephemeral Rollup documentation describes rollup state shielded inside an Intel TDX trusted execution environment, a sealed area of a processor that the machine running it cannot inspect, and lists trust in the hardware vendor as the trade-off.

The GitHub release notes cover the operator side: Token-2022 and sBPF v3 support, recovery of pending settlements, a terminal dashboard for validator operators, and a new replication service in which replica validators follow a primary. That last piece is unfinished. "Replica mode and the challenge protocol remains experimental in 1.0.0," the notes state, without saying when either will be finalised.

MagicBlock's fee schedule: 0.003 SOL per session and 0.001 SOL per commit

MagicBlock's blog post says the delegation session fee "will increase to 0.003 SOL, and the commit fee to 0.001 SOL". The post gives no effective date and does not state the earlier fees. MagicBlock's fee documentation, which says its values were checked on 20 August 2026, lists the same amounts: 0.003 SOL per delegation session, taken when the account is undelegated, and 0.001 SOL for each commit after the first. About 90% of what is collected goes to the validator and about 10% to the protocol, according to the same page.

Sessions and commits are the part of a rollup's life that touches Solana, and our own data gives a sense of the volume the fees apply to. Solana Compass analytics show roughly 770 to 950 transactions a day involving MagicBlock's Delegation Program on Solana in the seven days to 5 October 2026. That count covers base-layer transactions that call the program and excludes activity inside the rollups.

The blog post also introduces SOL rebates "for addresses that contribute a significant share of protocol activity". MagicBlock says it has selected an initial group of active delegators and invites other application builders to get in touch; it publishes no rebate rate or qualifying threshold. The company ties the scheme to a token it has not yet issued, writing that starting with SOL lets it "test and refine application incentives before the network token launches".

MagicBlock's post gives no launch date for that token.

Open-source code, developer docs and settlement on Solana

The validator source and release notes are in the magicblock-labs/magicblock-validator repository on GitHub, and integration guides are at docs.magicblock.gg. In its announcement on X, MagicBlock pitched v1.0 as a way for apps to "run in real time, prove every outcome is fair, and keep payments private, without leaving Solana".

Staying on Solana is the design choice that sets Ephemeral Rollups apart from a separate chain. Accounts start and end on the base layer, so an application built on MagicBlock keeps what the blog post calls "access to its programs and liquidity" while running its busiest moments elsewhere. Earlier examples include the mobile apps built at MagicBlock's Solana Blitz v6 hackathon in July 2026. MagicBlock has published no figures on how the new fees or the experimental replica mode perform under production load.
