DIEM Mint Rate History

What you're looking at

Venice's DIEM token uses an exponential bonding curve to set the mint rate (sVVV that must be locked to mint 1 DIEM). The formula is fully published, but the historical trajectory of the rate has never been tracked publicly. This page reconstructs it from raw on-chain data.

For each mint event, the rate paid is determined by the DIEM supply just before that event. By replaying every mint and burn event in order, we get the exact rate every minter actually paid, plus the supply trajectory that drove it. Rebuilding from events also surfaces the burn history (sVVV unlocks via DIEM burn), which is invisible on a price chart.

Methodology

1. Pull every Transfer(0x0, _, _) event on the DIEM contract via Alchemy alchemy_getAssetTransfers (mints).
2. Pull every Transfer(_, 0x0, _) event on the DIEM contract (burns).
3. Sort chronologically and walk through, tracking the running supply.
4. For each mint, compute the rate paid: 90 × e2 × (S/38000)³ where S is the supply at the start of the mint.
5. Reconcile the reconstructed final supply against on-chain totalSupply() (current run: zero drift).
6. Aggregate weekly snapshots for the chart and milestone crossings for the threshold table.

Dust events under 0.001 DIEM (deployer test mints + rounding artefacts) are filtered from the displayed event log but remain in the on-chain supply reconciliation.

A few things this dataset shows

• Launch day was a frenzy. On 20 August 2025, supply rocketed from zero to over 33,000 DIEM in hours, pushing the mint rate from 90 sVVV through 100, 150, 200 and 300 in a single day.
• The post-launch unwind was real. For weeks after launch, supply actually shrank as users burned DIEM to unlock their sVVV. That mechanism is invisible if you only look at price.
• Target was crossed on 15 April 2026. The mint rate hit ~665 sVVV (the rate the formula yields exactly at the 38,000 target supply) for the first time eight days into April. Past target, the curve goes near-vertical.
• Net flow is the right indicator of escrow direction. Today the supply lock is filling, but in the past it has been net-negative for stretches.

Effective float (the supply that can actually trade)

Total VVV supply growing tells you almost nothing on its own. What matters for price is the tradeable supply: total minus what's been permanently burned, minus what's locked in DIEM escrow. The chart below stacks all three and shows free float over the same window as the mint history above. Since DIEM launched in August 2025, free float has actually shrunk slightly even as new emissions added millions of VVV, because escrow plus burns more than absorbed the new issuance.
