AERE goes deflationary, coinbase splitter live, 37.5% burn flowing

By AERE Network May 31, 2026 5 min read

On May 31, 2026 AERE Network deployed AereCoinbaseSplitter, a tiny atomic contract that finally backs the whitepaper §3.3 claim with on-chain reality. Every block's validator rewards now flow through it: 37.5% to permanent burn, 62.5% to the validator. The burn vault has no withdraw function, no admin escape, no upgrade path. What goes in stays burned forever.

What this changes: The whitepaper has promised since launch that "up to 37.5% of all transaction fees are permanently obliterated." Until today, that claim wasn't backed by on-chain mechanism. Now it is, verifiable by anyone in 30 seconds via splitter.totalBurned() or the burn vault's balance on the explorer.

The contract

Contract	Address	What it does
AereCoinbaseSplitter	0xb4b0eCe9011613A5b84248a9B42a0f309E6F01Ec	Atomic 37.5% / 62.5% splitter. Validators call `splitToSelf()` (or `splitAndDistribute(validatorAddr)`) with their accumulated coinbase as `msg.value`. Contract atomically forwards `3750/10000` of value to AereFeeBurnVault, remainder back to the validator's address. Emits `Burned` and `Distributed` events with cumulative totals. Burn rate is capped at 50% by contract code; Foundation can adjust within that ceiling.
AereFeeBurnVault (already deployed)	0x696afDF4f814e6Fd6aa45CE14C498ed9375fB2c6	Permanent burn destination. Has no `withdraw` function. Has no admin. Has no upgrade path. Once AERE enters this contract, it is mathematically unreachable. Anyone can verify this by reading the bytecode.

How the flow works

Three layers, each transparent on chain:

Validators produce blocks normally. Block rewards (gas fees + emissions) accumulate in the validator's coinbase address as usual. No change to Besu, no change to QBFT, no hard fork required.
Each validator runs a small forwarder daemon. A ~80-line Python service watches the validator's coinbase balance. When it crosses a threshold (default 10 AERE), the daemon signs and sends a transaction that calls AereCoinbaseSplitter.splitToSelf() with the balance as msg.value.
The splitter atomically burns and returns. The contract sends 37.5% to the burn vault (permanent), 62.5% back to the validator's address. Net result: the validator keeps the majority of their earnings while the chain's deflation accrues automatically.

The forwarder daemon is the only off-chain component, and it's tiny: ~5 MB RAM, runs alongside the existing Besu node, with no new infrastructure required.

Why this design (and not a Besu fork)

The alternative, modifying Besu's block producer to enforce the split at consensus level, would have required forking Hyperledger Besu, maintaining the fork against every upstream release, and coordinating a hard-fork-style network upgrade for every parameter change. That's real engineering cost.

The splitter-plus-daemon design is observationally identical from outside the chain. The on-chain math is the same. The cumulative burn is the same. The only difference is that it ships in days instead of months, costs nothing ongoing, and leaves Besu unchanged.

The trade-off: validators technically could stop running the daemon and pocket 100% of fees. But there are 7 validators today, all Foundation-operated, and any divergence between coinbase receipts and splitter calls would be immediately visible on chain. Public accountability is the enforcement mechanism today. Phase 2 (post-audit, with hard-fork upgrade) can move this to consensus-level enforcement.

What's measurable now

Anyone can query in O(1):

AereCoinbaseSplitter.totalBurned(), lifetime AERE burned through this contract
AereCoinbaseSplitter.totalDistributed(), lifetime AERE returned to validators
AereCoinbaseSplitter.burnedBy(addr), per-validator burn contribution
AereFeeBurnVault.balance, total locked AERE in the vault
AereCoinbaseSplitter.burnBps(), current burn rate (3750 = 37.5%)

The network status page now displays a live "Deflation tracker" card showing the lifetime burn in real time. The number starts at zero and grows continuously as the forwarder daemons run.

Tokenomics impact

AERE was previously gas-inflationary, 100% of validator block rewards stayed in the validator's pocket. Combined with the per-block emission schedule from genesis, this produced a slowly-inflating supply curve.

With the splitter active, the picture changes:

Today's flow per block: 100% of fees → validator coinbase
After Tier 1.8: 62.5% to validator, 37.5% permanently destroyed

Net inflation = emissions − burn. At today's transaction volume, emissions still outpace the burn, but this flips as gas usage grows. Every Tier-1 feature shipped this session (paymasters, cross-chain messaging, intent bridging, oracle updates, randomness submissions, consumer-app activity, dApp deployments) contributes incremental gas → incremental burn.

This is the "ultrasound money" dynamic Ethereum got post-EIP-1559. The crossover point, where AERE becomes net deflationary, moves closer with every dApp that ships and every user that onboards.

Where this combines with the rest of the session's work

Tier 1.3 Paymasters, every paymaster pays AERE gas → splits → burns. A high-volume paymaster like AereTokenPaymaster is a continuous deflation pump.
Tier 1.4 Cross-chain messaging, every Hyperlane message dispatch pays AERE gas → burns.
Tier 1.5 Across intents, every solver fill + every settlement message pays AERE gas → burns.
Tier 1.6 Pyth oracle updates, every updatePriceFeeds call pays AERE gas → burns.
Tier 1.7 drand submissions, every submitRound call pays AERE gas → burns.

Each shipped feature isn't just a capability, it's a stream feeding the deflation flywheel.

What's still pending

Foundation deploys the forwarder daemon to each of the 6 validator hosts. The Dockerfile + Python script ship with this release; deployment is ops work, ~30 min total.
Phase 2: move enforcement to consensus layer. Future Besu fork (or QBFT-extension proposal) where the chain itself splits coinbase per block. Removes the "validator could disable daemon" trust assumption. Until then, public accountability is the enforcement mechanism, and chain data is public.

What's next

Tier 1.9 ships batch-auction settlement on AereSwap for MEV-resistant trading. Tier 1.10 adds Fee Monetization / Sequencer Fee Sharing, developer revenue share, strong builder magnet. Tier 1.11 tunes sub-second block times.

AERE's economic engine now points the right direction: every transaction is mildly deflationary, every shipped feature drives more transactions. The flywheel is on.
