Exchange migration guide

Use this guide to rebrand the original Terra chain as Terra Classic and integrate the new Terra chain. Please read this page entirely, as it contains important information. Check out the Exchange FAQ for answers to your frequently asked questions.

General info

Per governance proposal 1623, a new chain will be created and will assume the Terra name.

1. The original chain will still function and be re-branded as Terra Classic.

  • The original Cosmos chain will still run, with market swaps (mint/burn function) disabled.
  • All balances will remain as they are.
  • Luna will become Luna Classic (LUNC).
  • Terra stablecoins (UST, KRT, EUT, etc.) will be renamed Terra Classic stablecoins (USTC, KRTC, EUTC, etc.).

2. The new chain will be called Terra, and will assume all Terra branding assets.

  • The new chain is also a Cosmos chain, but will not have the treasury, oracle, or market modules of the original chain.
  • The new chain's native mining token will be Luna.
  • There will be no Terra stablecoins (UST, KRT, EUT, etc.) on the new chain.

Branding

The original chain will be branded Terra Classic. The new chain will assume the name Terra.

Naming convention:

Terra Classic

The original Terra chain will be rebranded as Terra Classic.

  • Official chain name: Terra Classic
  • All Luna currently on exchanges needs to be renamed Luna Classic (LUNC).
  • All Terra stablecoins will be rebranded as Terra Classic stablecoins. For example, TerraUSD(UST) will be renamed TerraClassicUSD(USTC) and TerraKRW(KRT) will become TerraClassicKRW(KRTC), etc.

Terra:

The new chain will assume the name Terra.

  • Official chain name: Terra
  • Luna (LUNA) will be the main staking asset of the chain.
  • The new chain does not support any Terra stablecoins (UST, KRT, etc.).
🔥Luna listing convention

It can be confusing to list the Luna coin as "Terra (LUNA)". To avoid unnecessary confusion, please stick to the following naming conventions for Luna:

For the Terra Classic chain, list as Luna Classic (LUNC)

For the new Terra chain, list as Luna (LUNA)

Logos and assets

Please update all logos and branding according to the following conventions:

Adobe Illustrator Terra Classic and new Terra chain logos.

Terra Classic:

The old chain will be rebranded using Terra Classic brand assets, including new logos for both LUNC and USTC. You will need to remove all current logos from the original chain and implement the Terra Classic brand assets on your exchange.

You can download these assets using the links below:

Terra:

The new chain will be branded with the following assets:

Mainnet launch schedule

  • 05/21 - The new Terra Core release is cut, network launch instructions made available for validators.
  • 05/25 - Essential app developer registration completed.
  • 05/27 - Genesis file created from final launch snapshot.
  • 05/27 - Network launch.

Snapshots and Airdrop

  • Pre-attack snapshot was taken at Terra Classic block 7544910 (7 May 2022 22:59:37 UTC+08:00).

  • Post-attack snapshot was taken at Terra Classic block 7790000 (27 May 2022 00:38:08 UTC+8:00).

Airdrop allocations

All airdrop allocations to UST and LUNA holders are based on the snapshots listed above. You may review the exchange-relevant allocations below. Note that these allocations exclude the Community pool allocation of 30% as it is irrelevant to exchanges. You may review the original token distribution text proposal on the Agora forum.

Note: Wallets owned by Terraform Labs are excluded from any airdrop allocations. Wallets owned by Terraform Labs will not recieve any token allocation at genesis.

Airdrop Calculation for Exchange

Pre-attack LUNA holders 35% allocation (350 M)


_5
35% * Total LUNA Supply * Total LUNA owned by Exchange pre-attack / Total LUNA supply pre-attack

= 0.35 x 1B x 10M / 1B

Pre-attack aUST holders: 10% allocation (100 M)

10% x Total LUNA Supply x Total aUST owned by Exchange pre-attack / Total aUST supply pre-attack

Use different seeds

To avoid user confusion and prevent the sending of funds to the wrong accounts, ensure that the Terra Classic and new Terra chain addresses have different seeds on your exchange. You may want to include a warning to users to make sure they are transacting on the correct chain and to the correct address.

Integration

Terra Classic:

The current primary LCD (https://lcd.terra.dev) and FCD (https://fcd.terra.dev) will continue to support the Terra Classic chain. However to ensure long-term support, please use https://columbus-lcd.terra.dev for LCD and https://columbus-fcd.terra.dev for FCD.

Terra:

The previous LCD (https://lcd.terra.dev) and FCD (https://fcd.terra.dev) endpoints will not support the new chain. To support the new Terra chain (phoenix-1), LCD should be altered to https://phoenix-lcd.terra.dev and FCD should be altered to https://phoenix-fcd.terra.dev.
