Notarization is rarely required for commercial side letters, but some jurisdictions or specific transaction types may demand it. Verify local notary rules and consider RON if permitted and needed for record authentication.

Can a side letter conflict with the main agreement?

Yes. Conflicting provisions can create enforceability disputes. Drafters should state whether the side letter amends or supplements the main agreement and include an integration clause to clarify precedence.

How do I revoke or amend a side letter?

Revocation or amendment requires the parties' mutual consent; follow any amendment or termination procedure stated in the side letter. Document changes in writing and obtain authorized signatures as required.

What a Token Side Letter Agreement Is

Token Side Letter Agreement is a short, supplemental contract executed alongside a primary token purchase or token issuance agreement. It records negotiated deviations, investor-specific representations, or procedural understandings about token allocation, vesting, transfer restrictions, and regulatory compliance measures. Typically used in private token offerings, the side letter clarifies deliverables, carve-outs, and confidentiality obligations between issuer and selected counterparties without amending the main token purchase agreement. Parties rely on it to document bespoke commercial terms, special rights, or carve-outs that apply only to particular token purchasers or strategic partners.

Why issuers and investors use a side letter

A Token Side Letter Agreement documents investor-specific rights, clarifies vesting or transfer exceptions, and addresses regulatory or tax considerations without changing the principal agreement. It reduces ambiguity and preserves tailored business arrangements between issuer and a narrow set of counterparties.

Common parties involved

Common users and stakeholders who prepare or receive Token Side Letter Agreements include issuers, investors, counsel, and corporate finance teams.

Token issuers and founders managing allocation, vesting, and strategic partner arrangements.
Institutional and accredited investors securing customized transfer or liquidity rights.
Corporate counsel and advisors documenting legal carve-outs and regulatory carve-out conditions.

Confirm roles, signatory authority, and internal approval pathways before signing to ensure enforceability and compliance.

Who typically signs

Issuer CEO

The issuer's chief executive generally signs when the side letter implements company-level commitments. Signing should follow board approval or a delegated authority resolution to ensure the signature binds the corporate entity and all internal approvals are documented.

Investor Counsel

An investor's legal representative may sign or countersign to confirm acceptance of bespoke rights and to note any regulatory or tax conditions. Counsel signatures are common where investors require protections such as escrow terms, AML confirmations, or specialized transfer restrictions.

Core sections found in a professional side letter

A clear Token Side Letter Agreement contains a small set of focused provisions that link to the main token purchase agreement while preserving bespoke terms for specific counterparties.

Parties

Identify each signing entity and role: issuer, investor, and any trustee or escrow agent. Include legal entity type and state of formation to avoid identity disputes.

Effective Date

Specify the effective date explicitly. This determines when bespoke obligations begin and can affect statutes of limitation and tax reporting windows.

Token Details

Describe token type, quantity, class, and any unit measures. Tie token delivery mechanics to the main purchase agreement to avoid operational gaps.

Consideration

State payment method and value (crypto or fiat). If tokens are issued for services, specify valuation methodology and timing of any payments or offsets.

Restrictions and Vesting

Document vesting schedule, cliffs, acceleration triggers, and lockup or transfer restrictions unique to the investor covered by the side letter.

Governing Law and Dispute Resolution

Name the governing state law and dispute mechanism (arbitration or court). Consistency with the main agreement avoids forum-shopping or conflicting processes.

Step-by-step: drafting to execution

Follow these steps to draft, review, and execute a Token Side Letter Agreement in coordination with the primary token purchase document.

01

Prepare Draft: Attach to principal token purchase agreement; reference relevant clauses.
02

Review Legal: Counsel reviews regulatory, tax, and securities risks.
03

Negotiate Terms: Confirm investor-specific rights, vesting and transfer concessions.
04

Execute: Sign, date, and circulate fully executed copies to parties.

Digital workflow settings to use

Configure a digital workflow so the side letter is stored and routed alongside the main token purchase agreement.

Field	Configuration
Document Link	Attach as Exhibit A or Schedule 1
Signing Order	Sequential or parallel signing; set routing
Authentication	Email link, SMS code, or KBA verification

Upload: Attach side letter as exhibit or schedule to main agreement.
Assign Signers: List issuer and investor signatories with roles and emails.
Authenticate: Use email, SMS code, or stronger ID verification.
Archive: Store executed copies with the primary agreement for records.

Risks and penalties from errors

Invalid Signatures: Missing authority can void terms

Conflicting Terms: Side letter contradicting main agreement

Securities Risk: Unintended securities offering exposure

Tax Consequences: Unclear tax treatment for token transfers

Penalties: Civil fines or corrective actions

Enforceability Issues: Improper execution reduces enforceability

Common drafting and execution mistakes

Failing to reference the primary token purchase agreement clearly, causing uncertainty whether the side letter modifies or supplements the main contract.
Using informal or ambiguous language for vesting, acceleration, or transfer restrictions that invites conflicting interpretations in enforcement.
Omitting signer authority verification such as board resolutions or delegated authority for corporate signers, which can invalidate the signature.
Neglecting to assess securities, tax, or AML consequences when granting bespoke rights, leading to regulatory exposure or retroactive corrections.

Key milestones from draft to archive

Track milestones to ensure side letters are negotiated, executed, and stored in alignment with closing schedules and regulatory windows.

01

Drafting

Prepare side letter text and attach exhibit references to the main agreement.

02

Legal Review

Counsel assesses securities, tax, and AML implications prior to negotiation.

03

Execution

Obtain authorized signatures; notarize or use RON if required or desired.

04

Recordation

Store executed copies with the principal agreement and preserve audit trail.

Timing considerations and deadlines

Match side letter timelines to the main agreement and any external reporting or closing requirements to avoid timing conflicts.

Execute Before Issuance:

Sign the side letter before token issuance or transfer to avoid retroactive disputes.

Vesting Commencement:

Confirm vesting start dates to align with issuance and tax treatment.

Acceleration Triggers:

Document conditions and dates that trigger accelerated vesting events.

Tax Reporting:

Align with tax reporting windows if token transfers create reportable events.

Record Retention Start:

Retention periods begin at execution or last effective amendment.

Illustrative use cases

These scenarios show how side letters resolve investor-specific needs without amending the main agreement.

Anchor Investor Liquidity

A lead investor requested a limited secondary sale window to improve liquidity

Short, specific carve-out for one investor
The issuer documented the carve-out in a side letter tied to the purchase agreement, preserving uniform terms for other investors while enabling the lead investor's exit plan.

Vesting Acceleration Carve-out

An investor required accelerated vesting on a strategic sale to align incentives

Event-based acceleration clause
Parties recorded the clause in a side letter so the main agreement remained standard for all purchasers while the investor gained tailored protection tied to a defined corporate event.

Practical tips for accurate execution

Adopt consistent drafting, signature, and storage practices to reduce disputes and ease audits.

Reference the Primary Agreement

Always cite the exact title, date, and parties of the main token purchase agreement and state whether the side letter supplements or modifies specific clauses.

Confirm Authority

Obtain evidence of signatory authority such as board resolutions or officer certificates for corporate parties to avoid later challenges to execution.

Use Clear, Specific Language

Define technical terms, token identifiers, and event triggers precisely to prevent conflicting interpretations between the side letter and the primary agreement.

Preserve Audit Trail

Capture timestamps, email trails, signer IPs, and digital certificates; store executed PDFs in an immutable record with indexing for retrieval.
