MANTRA Chain v7.0.0 — $OM to $MANTRA Redenomination

Summary

This proposal triggers the MANTRA Chain v7.0.0 software upgrade at Block 13,000,000 (target: ~3 March 2026). The upgrade implements the previously approved governance proposal ([Hidden link]) to redenominate the native token from $OM (uom) to $MANTRA (aMANTRA) and execute a non-dilutive 1:4 token split — increasing the hard-capped max supply from 2.5B to 10B tokens while preserving all economic value.

Release Details: [Hidden link]

Motivation

With the [Hidden link] complete as of January 15, 2026, this upgrade is the final step in MANTRA's brand harmonization. Aligning the chain's native ticker with the project name ($MANTRA) unifies the ecosystem — MANTRA Chain, MANTRA Finance, MANTRA Zone, and mantraUSD — under a single, globally recognizable identity. The 1:4 token split mirrors conventions used by comparable projects ($SUI, $ONDO, $ARB) and codifies the 10B max supply at the protocol layer.

What Changes

Unchanged: Chain ID (mantra-1 / EIP-155 5888), FDV, market cap, staking weights, governance weights, derivation path (44/60/0/0).

Technical Module Changes

All balances, parameters, and rewards are migrated automatically at the 1:4 × 10¹² ratio. No manual action is required from token holders, stakers, or delegators.

• Bank: All uom balances converted to amantra.
• PreciseBank: Fractional balances distributed to holder accounts (scaled 4×).
• Staking: BondDenom updated; validator delegations, delegator shares, unbonding delegations, and initial balances scaled.
• Distribution: Module account balances and outstanding validator rewards scaled.
• Governance: MinDeposit and ExpeditedMinDeposit scaled.
• Auth: All vesting account types (VestingPeriods, OriginalVesting, DelegatedFree, DelegatedVesting) migrated at defined ratio.
• Authz / Feegrant: Authorization spend limits and fee allowances migrated at defined ratio.
• EVM: evm_denom updated from uom to amantra.
• TokenFactory: denom_creation_fee updated from uom to amantra.
• Crisis: Constant fee scaled.
• Mint: MintDenom updated to aMANTRA.
• IBC Escrow (exception): IBC escrow accounts retain uom until funds return from destination chains (e.g., Osmosis), at which point they migrate to amantra. Post-upgrade, escrow accounts are the only entities that may hold uom.

Upgrade Mechanics

• Target block: 13,000,000 (~3 March 2026)
• Vanity block explorer: [Hidden link]
• At block height, the chain halts, v7 applies, and the redenomination executes atomically as a state migration.
• Upgrade handler: [Hidden link]

Governance Context

The token redenomination was approved by the community in [Hidden link] with 90.48% YES, 0.03% NO, and 9.49% ABSTAIN. This software upgrade proposal authorizes the technical execution of that mandate on mainnet (mantra-1).
