What You Just Watched
The AI demo in 4 steps
Protected Transfer
Funds enter configurable protected holding state.
Threat Detection
Address poisoning detected (97% similarity).
Autonomous Rewind
AI triggers rewind (policy-gated).
On-Chain Proof
Fragment NFT records AI safety action.
Detection is replaceable. The rewind primitive is not.
“Same protocol. Two permission models.”
Manual Mode
You control everything
- •Create protected transfers
- •Rewind anytime yourself
- •No delegation needed
- •Full manual control
You sign every rewind
Delegated Mode
AI monitors and rewinds for you
- •You create transfers normally
- •AI detects threats automatically
- •AI triggers rewind if needed
- •Works while you sleep
You must activate first · Disable anytime
Autonomy = Permissions, not Custody.
Both modes use the same protocol. You decide: keep full control or enable AI protection.

What is Rewind X?
Undo transfers before they're final.
A time-bounded safety window for ERC-20 transfers. Fully on-chain. Non-custodial. Deterministic.
Finally, safety without compromising decentralization.
Protected Transfers
2min–48h WindowEvery protected transfer enters a time-bounded state. The sender remains fully in control during this window. NFT holders may unlock extended windows (up to 48h).
Deterministic Execution
No Human DecisionsEvery action follows predictable on-chain logic. No operators, no approvals, no subjective judgment.
Non-Custodial Control
Full AuthorityFunds never leave the sender's authority. The protocol never holds custody and cannot intervene.
What it is
- Preventive safety layer
- Deterministic on-chain rules
- Sender-initiated only
What it is not
- Not insurance or recovery
- Not custodial
- Not changing finality
How It Works
Four deterministic steps to protect your transfers
Create Protected Transfer
Send any ERC-20 using protected mode. Funds enter a time-bounded, contract-held state (non-custodial).
- No admin keys can move funds
- Funds are held under deterministic on-chain rules
- State transitions are enforced by fixed on-chain rules
Active Undo Window (2min–48h)
The sender can initiate a rewind anytime during the active window.
- NFT tiers unlock extended windows up to 48h
- After expiry, rewinds are no longer possible; the recipient can finalize (pull-based)
Execute Rewind
The sender initiates the rewind. Automated on-chain checks validate hold time, deterministic rules, and integrity conditions.
- Balances update under deterministic logic
On-Chain Proof
Each successful rewind mints/updates a Fragment NFT: a tamper-evident audit artifact.
- Tamper-evident proof index
- Publicly visible on-chain
- Underlying records/events remain immutable
Built for Everyone
From everyday users to treasury operators. A deterministic undo window for ERC-20 transfers.
Retail Error Recovery
Wrong address, wrong amount, wrong token, duplicate payment. Time-bounded chance to undo sender errors.
Enterprise Ready
Multi-sig workflows, role separation, batched payouts, and verifiable on-chain audit trails.
Wallet Compatibility
Integrates with EVM wallets and smart account standards. Non-custodial by default.
AI Agent Safety
Agents execute protected transfers under explicit permissions. Rewind if flagged by policy.

RWXT is not required to use the core protocol. It is a software utility token for enhanced access features. It does not represent investment, yield, or financial return.
On-Chain Proof of Successful Rewinds
A transferable proof index. Minted on first rewind, updated with cumulative stats on each subsequent rewind.
Rewind X Fragment #1
Proof-of-Rewind · On-ChainTamper-evident Proof Index. On-chain audit trail for reversals.
Tracked Data:

Tamper-Evident Audit Trail
Updated with each successful execution. No fee discounts. Fragments are proof, not utility.

Cumulative Tracking
Tracks total rewind count, volume across all tokens, and valid executions.

Discounts apply to Protection Activation Fees only. Rewind execution fees are risk-based and not discounted.

Core transfer rules remain on-chain and deterministic.
Fair & Predictable Fees
A transparent dual-fee model designed for safety without hidden costs.
EOA Forward Transfers
1–3%
NFT tiers reduce the Protection Activation Fee portion by up to 50%. Rewind execution fees are not discounted.
This fee enables the deterministic safety window.
- Typical cost: 1–3% for normal EOA transfers
- NFT tiers can reduce this activation fee by up to 50%
- Fee applies per protected transfer
- Only charged again when initiating a new protected transfer
Determined by the protocol's on-chain Integrity Engine, which adjusts fees based on wallet behavior patterns:
- ~1.5% for established, normal wallets (typical case)
- Higher fees only for anomalous or high-risk patterns
- Bounded by a strict maximum cap enforced by protocol rules
- Fully deterministic. No manual approvals or overrides.
If you never rewind → you never pay this fee.
Reversal Models Compared
Traditional systems rely on custodial dispute processes. Crypto today offers no recourse. Rewind X introduces protocol-level, deterministic reversibility.
| Model | Custody | Reversal Type | Time Window |
|---|---|---|---|
| Chargebacks | Custodial | Discretionary | Days – Months |
| Bank Recall | Custodial | Manual | Uncertain |
| Crypto Today | Non-custodial | Irreversible | — |
| Rewind X | Non-custodial | Deterministic | 2min – 48h |

Security Principles
Built on transparency and trust minimization
Protected execution for operational transfers — strict finality for DeFi-critical flows.
Deterministic Execution
Rules apply equally to all users. No exceptions.
Trust-Minimized Controls
Administrative functions are bounded and cannot move user funds. Emergency pause can halt operations. Balances always remain in place.
Non-Custodial Fund Flow
Funds are held under deterministic smart contract rules during protected transfers. No admin keys can move them.
PREVENTIVE SAFETY LAYER · NOT RECOVERY OR INSURANCE
- Mitigates sender-side mistakes within a bounded time window
- Assumes standard wallet security practices by the user
- After window expiry, finality is absolute by design
Frequently Asked Questions
Everything you need to know about Rewind X
No. Rewind X is non-custodial: funds are held by smart contracts under deterministic on-chain rules. No admin key can move or redirect user funds. During the active window, only the sender can execute a rewind; after expiry, only the recipient can claim the held amount.
Only the sender who created the protected transfer can execute a rewind, and only while the rewind window is active. Receivers and third parties cannot rewind or cancel a transfer.
Windows are configurable from 2 minutes to 48 hours. Users select their preferred duration at transfer creation. NFT tiers unlock extended windows up to 48h. After expiry, the transfer becomes claimable by the recipient. No rewinds are possible beyond the window.
Protected transfers settle as net amounts: the protection fee is deducted at creation, so the recipient receives the held (net) amount. If a rewind is executed, the sender recovers the held amount minus the rewind execution fee.
No. Rewind X operates entirely at the application layer. Chain finality is unchanged. The protocol simply adds a deterministic safety window before final settlement.
No. Any EVM-compatible wallet can interact with Rewind X. Protected transfers work using standard ERC-20 approvals and do not require allowlists or special infrastructure.
Rewind X includes multiple automated safeguards: daily sender limits, tier-based cooldowns, behavior analysis for fresh wallets, and circuit breakers for abnormal patterns. All protections are deterministic and non-custodial.
No. During the active rewind window, only the sender can act. The recipient cannot claim early. After expiry, the recipient must claim (pull-based) to receive the held amount.
Yes. The sender can waive their rewind right before the window expires, making the transfer immediately claimable by the recipient. This is useful when both parties want faster settlement.
After the window expires, the transfer is finalizable by the recipient (pull-based). If the recipient never finalizes, the net amount remains held under deterministic contract rules until it is finalized. It is not auto-released or returned by the protocol.
Rewind X supports all ERC-20 tokens. Native chain tokens (ETH, BNB, MATIC) require wrapped versions such as WETH or WBNB.
RWXT is used to acquire optional NFT utility tiers that unlock enhanced protocol parameters: fee discounts on protection activation, extended windows (up to 48h), higher daily limits, batch operations, and team wallet controls for enterprise users.
