ERC-20E
Overview
Built by Elevado, ERC-20E extends the ERC-20 token standard by embedding complete economic logic into a single monolithic contract, transforming a simple balance ledger into a self-contained, programmable financial instrument.
ERC-20E defines a new class of asset primitives that are:
Reserve‑backed and fully collateralized
Collateral-denominated
Monotonically non-decreasing NAV
Deterministic and oracle‑free
Endogenous yield‑bearing
Insolvency‑proof
Fully decentralized and governance-free
Fully permissionless, trustless, and credible neutral
Monolithic and immutable
Unlike traditional ERC‑20 tokens (which only specify balance and transfer logic), ERC‑20E encodes a full economic system where issuance, redemption, collateral custody, valuation, accounting, and yield accrual are all defined on‑chain by a single monolithic smart contract.
As a core economic feature, ERC‑20E incorporates a Net Asset Value (NAV) formula that establishes a cryptographically enforced value floor, ensuring that each token’s per-unit backing (1) is monotonically non-decreasing; (2) increases at every mint or redemption, and (3) remains fully insolvency‑proof at all times.

Properties
Reserve‑Backed and Fully Collateralized
ERC-20E enforces strict reserve accounting at the contract level, where token supply expansion is only possible through deterministic collateral deposits governed by the NAV formula.
Tokens may only be minted through the authorized mint function, which requires collateral to be deposited in accordance with the prevailing NAV. There is no mechanism to expand supply without corresponding collateralization. Each unit of newly issued supply is backed at issuance by verifiable on-chain collateral.
Redemptions require tokens to be burned before collateral is released. Collateral withdrawals are strictly proportional to the NAV entitlement of the redeemed tokens, preventing over-withdrawal or reserve imbalance.
As a result, ERC-20E maintains a continuously verifiable collateral floor. Solvency is not assumed or governed, but structurally enforced by immutable issuance, redemption, and accounting rules embedded directly in the contract logic.
Collateral‑Denominated
ERC-20E assets are natively denominated in units of their underlying collateral. The token’s unit of account is the collateral itself, and all economic state transitions are defined directly in collateral terms.
NAV, mint issuance, redemption payouts, and yield accrual are calculated exclusively as quantities of the deposited collateral. Each token represents a dynamically adjusting claim on a specific amount of on-chain collateral.
Because valuation is expressed entirely in collateral units, the asset’s economic state is fully determined by deterministic supply and reserve mechanics. As a result, ERC-20E tokens function as mathematically defined collateral entitlements, with value emerging from on-chain reserve growth.
Monotonically Non‑Decreasing NAV
ERC-20E enforces a deterministic Net Asset Value (NAV) invariant under which the per-token collateral backing can never decrease as a result of protocol-defined state transitions.
More strongly, NAV increases with every mint and every redemption. This behavior is driven by protocol fee retention and proportional accounting: protocol fees are always retained within the system, so each mint or redemption increases the collateral held relative to outstanding supply. The result is a value floor that increases at every protocol interaction.
Deterministic and Oracle‑Free
ERC-20E derives all economic quantities – including NAV, minting, redemption, and fee accrual –entirely from on-chain state. No external price feeds, oracles, or off-chain inputs are required for calculations. Every state transition is deterministic, fully verifiable, and auditable on-chain, ensuring that token valuation and collateral accounting are predictable.
Endogenous Yield
ERC-20E internally generates yield through protocol fee retention. Fees collected on minting, redemption remain within the reserve, increasing collateral relative to outstanding supply. This automatically raises NAV, creating a non-dilutive, endogenous yield that accrues to all outstanding supply without external inputs.
Insolvency‑Proof
ERC-20E is structurally designed to guarantee solvency at all times. Every token is fully backed by collateral, and redemptions are strictly limited to the collateral corresponding to outstanding supply. The protocol’s accounting invariants prevent over-withdrawal, ensuring that total obligations never exceed reserves.
Solvency is not assumed or managed externally, but mathematically enforced by the contract’s deterministic minting, redemption, and fee retention logic.
Decentralized and Governance‑Free
Once fully bootstrapped, ERC-20E smart contracts operate without any privileged control or governance intervention. All core economic functions – including collateralization, NAV computation, issuance, and redemption – are immutable and enforced purely by contract logic.
No individual, entity, or governance mechanism can modify protocol behavior, ensuring complete neutrality, predictability, and trustlessness. The system is fully decentralized: token holders interact with deterministic, on-chain mechanics, free from discretionary control or centralized authority.
Permissionless, Trustless, and Credibly Neutral
ERC-20E contracts are fully permissionless. All operations – including minting, redemption, and NAV settlement – can be executed directly by any participant without approval or intervention from any authority.
Interaction occurs solely through deterministic contract logic, ensuring trustless execution, predictable outcomes, and credible neutrality. No centralized actor can influence state transitions or economic behavior of ERC-20E smart contracts, preserving the integrity and autonomy of the system.
Monolithic and Immutable
ERC-20E is implemented as a single, self-contained contract, consolidating all financial and economic logic in one monolithic architecture.
In addition, ERC-20E contracts are fully immutable: once deployed, the contract’s behavior cannot be altered, ensuring that collateral management, NAV computation, minting, redemption, and fee accrual remain deterministic, auditable, and resistant to systemic risk from external dependencies or upgrades.
